Cloudless Sulphur on lantana, Behnke's Nursery 2013 [REB]

Cloudless Sulphur on lantana, Behnke’s Nursery 2013 [REB]

The traditional end-of-summer holiday weekend should provide good opportunities – albeit hot and hazy ones – to go afield in search of wandering migrants.

In recent weeks, the numbers of Variegated Fritillaries has been inching up locally, and reports of Ocola Skipper remain uncommon but consistent. New to the region this week is Long-tailed Skipper from northern VA, which leads to the hope that others are in the area as well. Clouded Skipper is being reported regularly in VA and NC so should be showing up as well; there are a number of reports of Gulf Fritillaries to our south that suggest this might be a good migrant year for them. Cloudless Sulphurs are finally showing up locally, including two today at Pt Lookout State Park MD.

But the current big tease is the explosion of Little Yellow and Sleepy Orange in NC and VA, in numbers that in other years have signaled a good fall push into the upper mid-Atlantic. Sleepy Orange showed up this week for the first time this season in the Plummer House garden at Jug Bay (Anne Arundel Co MD). Common Buckeye is also building in numbers to our south; true to its name it was common but not abundant this week at Pt Lookout State Park in MD.

Otherwise, numbers and diversity are not too far off the mark from what you’d normally expect at the beginning of the fall flight season. Leonard’s Skipper has not been observed in MD yet, but is flying well from PA to MA. Grass skipper numbers are up; most lantana patches locally (including big box garden centers) have yellow clouds of Sachem and Fiery Skippers. Tawny-edge, Zabulon, Dun, Swarthy, and Crossline Skippers are still present given good nectar sources, and Southern Broken-dash numbers are still quite high.  Silver-spotted Skipper is winding down its flight.

A new brood of Northern Pearly-eye is on the wing, and seems to be expanding its range in the mid-Atlantic. Common Wood-nymph is still flying.  Carolina Satyr and Appalachian Brown were observed in St. Mary’s Co MD.  Tawny Emperor was still flying there as well.

On the swallowtail front, another local Giant Swallowtail sighting, this week from Baltimore. Pipevines are out and fresh, as are Black Swallowtails. Pipevines can even be seen in good numbers near the Smithsonian Castle on the National Mall, where a couple of large, interesting tropical Aristolochias are planted in the Enid Haupt gardens. A Spicebush Swallowtail was there yesterday as well, also in very fresh condition. Eastern Tiger Swallowtails are having a relatively modest late summer flight; most are showing considerable signs of wear already.

Grey and Red-banded Hairstreaks are having a good late flight; at Pt Lookout (St. Mary’s Co MD) today Grey Hairstreaks were abundant and Red-banded were common; two White-M Hairstreaks were also seen there mixed in with the Greys and Eastern Tailed-blues. Pearl Crescent is seen on most field trips but in nowhere near the numbers we usually find in late summer.

Dick Smith announced two field trip opportunities this weekend:

  1. August 31: Serpentine Barrens Late Summer Butterflies – Slide Show and Hike, Soldiers Delight NEA, 1-4pm. Dick Smith will present a slide show *(handicap accessible) on barrens butterflies and then lead the group for about 2 miles along trails *(not handicap accessible) through the globally rare serpentine barrens ecosystem at Soldiers Delight. In addition to locally-occurring and serpentine-endemic late summer butterflies such as the attractive Leonard’s Skipper, we will examine and identify many native grasses and wildflowers seldom seen in abundance in other locations around Maryland. Close-focus binoculars are recommended, but butterfly net-and-release (with in-jar identification) will be conducted by the leader. Hike will be cancelled if raining or overcast, but slideshow will be presented regardless of weather status. Children under 12 should be accompanied by an adult. Meet at the Visitor Center. Cost: Free! Donations welcome. Registration is not required; CONTACT: (443) 778-4973 (office – weekdays, 9:00 a.m. to 6:00 p.m.) or (410) 997-7439 (home) (please call after 7:30 p.m.).
  1. Butterflies through Binoculars in Columbia. 2-3 hours. Meet 9:30 AM at Elkhorn Garden Plots (Oakland Mills Rd opposite Dasher Ct). Enjoy searching for late-summer butterflies, and receive expert instruction on their identification. Easy walking in the garden plot and on paved paths near the right-of-way alongside open, flowery wet meadows and brushy hillsides. Bring close-focus binoculars to view nectaring behavior. Dick will also use net and jars to provide brief close-up examinations. Cancelled if raining or overcast. No facilities. CONTACT: Dick Smith, 410-997-7439. (home, please call after 7:30 pm)

If you spend time in the field this Labor Day, please remember to post or send your sightings for the next Weekend Forecast. In the meantime, visit us at and on Google Groups at MDLepsOdes.

Walking the pine plantation on the way to the Cranesville Swamp boardwalk

  Our three-day Audubon Naturalist Society extended foray began in early afternoon on Saturday July 19 at Finzel Swamp, a boreal relict fen in eastern Garrett County. Unfortunately, we started in drizzle and ended in steady rain. Despite the showers, we managed to kick up some Finzel butterfly specialties early in our trip: Black Dash, the very dark northern form of Common Wood-nymph, and Appalachian Brown. We also had a few more common leps, including Eastern Tailed-blue, Pearl Crescent, and Great-spangled Fritillary. We sorted through a few odes in the meadow at the parking lot, including White-faced Meadowhawk (and possibly a second meadowhawk species), a couple of damselflies, and a Slender Spreadwing.

Other insects of note included panorpid scorpionflies, Virginia Ctenucha day-flying moths, and a couple of diminutive pyrodoxine Yucca Moths buried deep in yucca flowers at the old homestead. We talked at length about the mutually beneficial relationship between the pollinating moth and its host; the moth pollinates the flower in exchange for a few of the ripening ovaries to feed its caterpillars.

Birds were notably hunkered down, but brief let-ups in the rain gave us Black-capped Chickadees, Purple Finch, Swamp Sparrow, Rose-breasted Grosbeak and hosts of Cedar Waxwings cleaning up on black cherries. The human participants cleaned up on ripe blueberries.

The plants didn’t mind the rain nearly as much; we explored the many microhabitats created by varying water levels, from deciduous holly, to blueberry, to speckled alder. We also discussed the nutrient cycle in this nutrient- poor environment, and how changes in the hydrology of the Finzel area — including contamination with fertilizers — could tip the balance in favor of the invasive European plants that we saw on the path and around the margins of the fen as just trace amounts of fertilizer allow invasives to outcompete native flora that are adapted to the poor nutrient habitats. The large white Rhododenrons were blooming along the small pond’s edge near the parking lot.

We enjoyed a group dinner at The Hen House in Frostburg. The optional night hike at Finzel was called off because of the continuing rain.

Day two came very early, with a dawn hike for those who wished just south of Frostburg to a known location for Henslow’s Sparrow. About half the group showed up in the hotel parking lot for the carpool down, and after a short hike into an overgrown pasture, we were able to get crippling views of Henslow’s and Grasshopper Sparrows, at one point posing within inches of each other on the same shrub and both singing – you couldn’t ask for a better side-by-side comparison of these two grassland sparrows! We talked at length about how weedy pastureland and grasslands are among Maryland’s most endangered habitats while watching Eastern Meadowlark and listening to Field Sparrow, Indigo Bunting, and other grassland birds singing as the sun emerged from the clouds.

We returned to the hotel, gathered the rest of the tour group, and headed west to Cranesville Swamp on the MD/WV border in the expectation of seeing Bog Copper, a specialist butterfly restricted to bogs where its host plant, small cranberry, creeps across the sphagnum floor of the bog. After a short hike in – with a number of Appalachian Browns along the way, and some fast-flying Great-spangled Fritillaries – we emerged onto the boardwalk and spent about 15 minutes looking for the coppers. While we looked for the butterflies, we also saw two odonate denizens of Cranesville – large, blue Spatterdock Darners and the diminutive Sphagnum Sprite damselfly. Bog plants in abundance also caught our attention, from American larch to carnivorous sundews to pale green orchids and myriad sedges and rushes. Finally, a burst of bright sunshine through the cloudy skies brought out a good number of the Bog Coppers, affording good views for everyone. The walk back provided good looks at plants more at home in the Maine woods than Maryland: trailing arbutus, dewdrops, wintergreen, and Turks-cap lily, as well as the original coniferous inhabitants of the area upslope from the bog, white pine and hemlock. Overhead, we heard singing Golden-crowned Kinglets and Red-breasted Nuthatches in addition to the lazy whistles of Black-capped Chickadees; group members “pished” up a Yellowthroat that followed us for a good distance along the trail, scolding the entire time. As we returned to the parking lot, we discussed the essential differences between the bog-like habitats at Finzel and Cranesville, a conversation we continued over lunch in McHenry.

After lunch we continued our foray in Garrett County with a visit to Herrington Manor State Park. Our first stop there was the Grow No Mow meadow, a managed field near the lake with abundant wild oregano, heal-all, and scattered dogbane. This field provided some of our best butterflying of the trip, with ample opportunities to study the differences between the very similar Great-spangled Fritillary and Aphrodite Fritillary; more Black Dashes; the small Meadow Fritillary; many Common Wood-nymphs and Appalachian Browns, both sipping fermenting sap from a tree wound; our first Northern Pearly-eye of the trip; and Dun, Crossline and Little Glassywing Skippers in addition to the by-now-ubiquitous Silver-spotted Skipper. American Copper gave us our second copper species of the trip.

Damselflies shared the meadow with the butterflies,

and several large dragonflies – Twelve-spotted Skimmer, Common Whitetail, and Widow Skimmer – hawked for midges and mosquitoes. Calico Pennant dragonflies staked out the tops of the taller grass stalks.

Just downhill from the meadow we explored the lower margins of the parking lot, with even better opportunities for comparing fritillaries. But the scene-stealer here was a Meadow Jumping-mouse that afforded very good looks as it huddled in the short grass.

Closer to the lake we picked up more butterflies, including our first swallowtail of the trip, Eastern Tiger Swallowtail. Orange Bluet damselflies hung out along the lake edge, and Variable Dancers among others haunted the tall grass under the berm. Two Spotted Sandpipers flushed up, giving everyone a good look at their teetering exploration of the muddy shoreline.

As the sun lowered, we made one last stop before returning to Frostburg: Snaggy Mountain Road, a short dirt road through hemlocks that provided an evensong of Hermit Thrushes and good but distant looks at a Scarlet Tanager. Snaggy also gave us good close-up looks at the flowers of Turks-cap Lily.

Offers to reschedule the Finzel night walk from the night before were turned down as the exhausted troops opted for an early night!

Day 3 had a leisurely start as we waited for the sun to rise over the hills in Green Ridge State Forest and warm the shale shoulders of the woodland roads through the Sideling Hill Creek drainage. On the way to Green Ridge from Frostburg we stopped first at the State Forest visitor center, where – unbeknownst to us – the restroom facilities were closed owing to a septic problem. We walked the short path to the overlook, where we had additional close-ups of Scarlet Tanager and enjoyed a lively discussion of the finer points of flycatcher ID as we watched an Eastern Wood-pewee darting out from dead branches near the overlook. A skipper on the ground next to the path proved to be a Horace’s Duskywing, leading to a good conversation about the essential differences between the grass skippers and the spread-wing skippers, and a refresher on moths, skippers and butterflies more generally. From the overlook platform we also could see at least six species of oaks, and talked about the remarkable genetic promiscuity of oaks in general and how the areas of mixed-growth forest like Green Ridge are hotspots of genetic diversity and speciation, as opposed to landscape-like plantings in urban settings and monocultures on tree plantations.

Before descending into the lowlands of the state forest, we stopped at the Citgo gas station at High Germany Road. The moths must have known it was the start of National Moth Week – the lights at the convenience store the night before had pulled in tremendous numbers of moths, fishflies, stoneflies, Dobsonflies, beetles, and other nocturnal insects. We knew we were in for a treat when our first sight was eight – EIGHT! – huge Imperial Moths and a Royal Walnut Moth right off the bat. There were dozens of Dobson-flies, including several large-mandibled males. Other moth sightings included The Angel, Pandorus Sphinx, Rosy Maple Moth, Beautiful Wood-nymph, Clymene Moth, Banded Tussock Moth, and a variety of geometers, emeralds, tiger moths, and others.

The early morning fog was lifting as we left the gas station and

drove into the state forest along a shale-lined roadside with tall golden woodland sunflowers along the shoulder. Sure enough, several of these sunflowers sported small brown butterflies with intense coppery undersides – Northern Metalmarks! – found here where their food plant, the shale barren obligate round-leaved ragwort, occurs in conjunction with the sunflowers for adult nectar.

After everyone had their fill of metalmarks, we moved down along the banks of Sideling Hill Creek, where our first sighting was of a Louisiana Waterthrush on the far bank. The muddy shoreline and rocks provided lots of good dragonflies and damselflies, including Powdered Dancer, Black-shoulder Spinyleg, and Stream Bluet. Spiders included a huge-jawed tetragnathid, an orb weaver with fangs that fold in half and that builds its webs horizontally over streams and ponds to capture emerging midges and mayflies, and a Dark Fishing Spider clinging to a rock in the stream. Also on a rock in the stream was an imperturbable Northern Banded Watersnake. Birds in addition to the waterthrush included Northern Parula Warbler carrying food. Along the road we saw a blue-tailed skink – Five-lined or Broadheaded – wedged into a massive Poison Ivy vine. As we left, a Spicebush Swallowtail sailed in to explore some of the streamside phlox.

Several group members peeled off at this point, the last official stop of the trip, but a couple of die-hards accompanied me up onto the ridge over Sideling Hill Creek along Hoop Pole Road for more metalmarks, a Pipevine Swallowtail, and a completely surprising Common Roadside-skipper. With clouds rolling in again right on schedule, we ended our western Maryland field experience and headed back to DC to beat the afternoon rush hour.

Regal Fritillaries mob milkweed on the 2013 Ft. Indiantown Gap tour

From the official news release:

This July, visitors are invited to see the only population of rare Regal Fritillary butterflies in Pennsylvania at Fort Indiantown Gap, near Annville, Lebanon County.Free guided tours will be given at 10 a.m. on July 4, 5, 11 and 12.

Those wishing to attend should arrive at least 30 minutes early to fill out necessary paperwork, attend a mandatory safety and orientation briefing, and receive driving instructions. Tours will last approximately three hours, but attendees can leave earlier if needed.The tours, which have been offered for more than 10 years, allow the public to see this rare butterfly and its associated habitat on military training ranges, as well as many other natural spectacles on the 17,000-acre military post, which serves as the Pennsylvania National Guard’s headquarters.

The Regal Fritillary is considered a Pennsylvania invertebrate species of immediate conservation need.”As one of the busiest National Guard Training Centers in the country, Fort Indiantown Gap is also a leader on the environmental forefront because we place a very high priority on being environmentally aware,” said Lt. Col. Robert Hepner, commander of Fort Indiantown Gap. “These butterfly tours, given by our biologists, provide excellent insight on not only the regal fritillary butterfly but also on the flora, fauna, and wildlife that inhabit beautiful Fort Indiantown Gap and our dedication to safeguard these spectacular natural resources.”

Participants should meet at the Fort Indiantown Gap Recreation Center in Building 13-190, located at the intersection of Asher Miner Road, Clement Avenue and Route 443 (GPS coordinates in decimal degrees: North 40.431, West 76.591).Visitors of all ages are encouraged to bring cameras and binoculars and should wear appropriate clothing and footwear for a nature walk on well-maintained trails or mowed paths. Feel free to bring insect repellent, sun screen, and other personal comfort items. Drinking water will be provided. No reservations are required and no rain dates will be scheduled.The tours also will include information related to current efforts to restore native grassland habitat across Pennsylvania and current efforts to raise Regal Fritillary caterpillars from eggs in a lab with support from the PA Wild Resource Program and in partnership with ZooAmerica North American Wildlife Park and Pennsylvania State University. The ultimate goal is to return the Regal Fritillary to areas where they were located in the recent past.

Fort Indiantown Gap is home to 112 Pennsylvania Wildlife Action Plan priority species. It also provides a wide variety of habitats for 36 species of mammals, 143 breeding species of birds, 34 species of reptiles and amphibians, 25 species of fish, 792 species of plants, and many notable species of invertebrates including 85 species of butterflies and 243 species of moths. The installation also features 1,000 acres of scrub oak and pitch pine barrens and over 4,500 acres of native grassland habitat – the largest in the state.Fort Indiantown Gap is the only live-fire, maneuver military training facility in Pennsylvania. It balances one of the region’s most ecologically diverse areas with a military mission that annually supports 19,000 Pennsylvania  National Guard personnel and more than 130,000 other states’ Guard, military, law enforcement, and civilian personnel each year.

Palamedes Swallowtail on Swamp Milkweed, 2013 July 27, Pocomoke City MD

Palamedes Swallowtail on Swamp Milkweed, 2013 July 27, Pocomoke City MD

Both numbers and diversity have been picking up over the past week, building into what looks like it might be a very productive August, so different from the lep slump that has been much of the summer season so far.

The butterfly garden at the Parris Glendening Preserve’s Plummer House in Lothian was the hoppin’ place to be for butterflies on Monday, with four Southern Cloudywings at the top of the list.  This incredible small garden – with lots of lantana, several species of milkweed, zinnias, and verbenas, plus host plants of various kinds – also hosted multiple Sleepy Oranges, Cloudless Sulphur, American Snout, and an assortment of grass skippers including large numbers of Dun, Crossline, and Peck’s.  The Cloudless Sulphurs are showing up pretty much everywhere these days, with several booking it across the Beltway just this morning on my drive to work.

King’s Hairstreak was looking worn but viable still on Saturday at its location along Careytown Branch near Whaleyville MD.  The key, I’ve discovered, is that like many satyrium hairstreaks they retreat back into the canopy pretty early in the day so catching them before the sun is very high and the dew is still on the ground seems the best option.

Maryland also apparently supports at least one relatively robust population of Palamedes Swallowtail along the swamps of the Pocomoke River east of Pocomoke City.  At least seven and probably many more (they were not nectaring but skittering around through the dense vegetation) were seen on Saturday.  In the same general location were Great Purple Hairstreak, more American Snouts, and building numbers of Cloudless Sulphur, Common Buckeye, and Variegated Fritillary.  Clethra is in full bloom there and elsewhere on the Eastern Shore now and was drawing in dozens if not hundreds of Eastern Tiger, Spicebush, and Zebra Swallowtails.  Silver-spotted Skippers were flying in the hundreds.

Fresh Juniper (Olive) Hairstreaks have been reported at a number of locations, especially in PA, this week.  Likewise, Zabulon Skipper (mostly males so far) is emerging for its next flight.  Viceroys have also been popping up in DE, PA, and MD.

The Monarch drought seems to be ending, with sightings this week in good numbers on the MD and DE Eastern Shore, PA, CT, VT, MA and elsewhere up and down the seaboard, although not in numbers we often see them.  Still, plenty of time to recover population density before the southward migration.  Most of the ones I was seeing appeared to be locally eclosed – very fresh and showing little or no signs of migration wear.

Hessel’s Hairstreak made an appearance in an Atlantic white-cedar swamp in Moore Co NC, nectaring late in the day on sweetshrub.  Ten Lace-winged Roadside Skippers shared this habitat.  Hoary Edge was still on the wing in Moore Co as well, in the Sandhills Community College Gardens, along with Fiery Skipper, Southern Cloudywing, and Whirlabout.  Several Mottled Duskywings were among the species seen at the Sandy Mush Game Lands in Buncombe Co NC on Sunday.  We could see Whirlabout here in the DC metro area this year; seems to be the start of a good flight of these Fiery Skipper-look alikes; it was also seen at the Pitt County (NC) Arboretum on July 30.  Ocola Skipper was found there on Monday as well; another one to watch for in the DC area on days following strong breezes from the south.

A last brood of Summer Azure is emerging now that will fly through early September; David Wright points out in a PaLepsOdes posting that these autumn azures frequently present with broader black borders and considerably more ventral spotting, occasionally showing up as f. ‘marginata’ with a brownish-black margin on the underside of the hind wing.  Red-banded Hairstreaks seem to be making a better showing with a summer flight than they did this spring, when they were very hard to find.

Harvester was reported ovipositing among woolly aphids near Pittsburgh PA this week; here in the DC area there haven’t been enough aphids to support a Harvester hunt, although the recent warm, humid weather might bring on more.

OF SPECIAL NOTE:  For those of you weathering the August heat on the Outer Banks or elsewhere in the Carolinas, the Carolina Butterfly Society has a number of opportunities for field explorations (info courtesy of Dennis Burnette; email below):

Aug. 10, Sat. — Carolina Butterfly Society will have an official butterfly walk at the Latta Plantation meadow and power line path and at Cowan’s Ford WR fields in Mecklenburg County near Charlotte. The event is being organized by Carl Ganser, who is on the CBS board. More information will be sent out, but you can contact Carl right now for details at, cell 312-351-5350.

Aug. 17, Sat.  — The Triad Chapter of CBS will hold a butterfly walk at Haw River State Park in Guilford Co. Well explore the power line right of way and woodland edges near the wetlands in this relatively new state park on the Guilford/ Rockingham County line. Leader: Dennis Burnette <>

Aug. 22, Thurs. — Rockingham County Butterfly Count. Counts are like regular butterfly walks except that a designated person records the species and numbers of individual butterflies we see and reported to the North American Butterfly Association. Beginners are welcome. Contact: Brian Bockhahn <>

Aug. 25, Sun.  Official Carolina Butterfly Society field trip: Carolina Sandhills National Wildlife Refuge, McBee, SC. Because of the potential heat, we will drive various parts of the refuge, getting out of our air-conditioned cars to investigate when we see butterflies. Leader: Dennis Forsythe <>

Please let me know what you’re finding out there so I can pass it along to other readers of the Forecast!  Follow mid-Atlantic butterfly sightings at and on Google Groups at MDLepsOdes.


For those of you headed out into the field over the long weekend, here are some notes that might influence your travels.

Spring flights of most species are over, and we won’t see many of the univoltines until next spring.  Second broods are emerging for a number of common species, and we’re noticing the first push of southern migrants into the area.  Things to watch for this long holiday weekend:
The area’s FOY Cloudless Sulphurs (Dorchester Co.; Little Bennett Regional Park) and Fiery Skippers (National Arboretum) were noted this week.
Grass skippers are showing up as second brood, with fresh Little Glassywing, Peck’s, and Dun Skippers on the wing across the area.  New brood Zabulon is not yet noted as flying.  Closer to the Bay and coast, Salt Marsh, Broad-winged, Aaron’s and Delaware Skippers were abundant at Eastern Neck NWR in the butterfly garden.  Rare Skipper was nectaring on buttonbush along DeCoursey road last weekend.  European Skippers are superabundant in Finzel Swamp and other western Maryland and West Virginia locations; Hobomok is just finishing up at Finzel but both Long Dash and Black Dash are in good flights.
On the swallowtail front, new broods of Black, Zebra, and Eastern Tiger Swallowtails are on the wing, which means we should keep an eye out for Giant Swallowtail second brood.  Like last year, Giant Swallowtails are being seen regularly in the Northeast (Maine, New York, Massachusetts, Rhode Island, Vermont) and in the Carolinas.  Here in the mid-Atlantic, Giants have been scarce, with sightings mostly along the Potomac at various locations, especially in western Maryland.  Second brood has not yet been seen.  Fresh Pipevine Swallowtails are working the huge Aristolochia vines over the National Herb Garden gazebos at the National Arboretum.
This is proving to be a banner year for Satyrium hairstreaks, especially Coral Hairstreak, which has been seen in numbers at various locations in the DC metro area (especially along the Northeast Branch trail in College Park) and in Delaware (along the MD/DE line near Delmar).  Any patch of common milkweed or butterfly weed is worth checking out.  Striped and Banded Hairstreaks are beginning to fade from a strong flight in June, but Edwards’ Hairstreak has just begun to fly in the Frederick Watershed Forest this past weekend; it has been flying for a few days longer than that in the Northeast states.  Red-banded Hairstreak should be in a second brood soon if it isn’t already; this was a rather scarce species this spring.  Olive Hairstreak should also be looked for about now in its second flight.  The elusive King’s Hairstreak was not yet flying at its best-known location on the Eastern Shore, assuming of course that yours truly and colleagues overlooked it on our hunt for this species on June 29.  It is, however, on the wing just to our south in Virginia and North Carolina.  Great Purple Hairstreak is showing up on dogbane and buttonbush at its regular spots in Dorchester Co.
Common Buckeyes are beginning to show up in some numbers on the Eastern Shore, so should be expected most anywhere in the mid-Atlantic.  A new brood of Red Admiral – rather scarce this spring – has emerged in various locations.  Fresh American Lady has been spotted across the region, but Painted Lady is still very uncommon.  None of these three species is present in anywhere like the huge irruptive numbers of 2012.  Anglewings seem mostly to be in summer torpor; a fresh brood has emerged and was seen in mid-June but they will mostly aestivate during the hottest days of summer and re-emerge (and overwinter) later in the year.  Common Wood Nymph is having a strong flight on the Eastern Shore, especially in the milkweed field across from the temporary visitor center at Blackwater NWR.  This is an exceptionally dark, almost black, form.  And here’s a reminder that Harry Pavulaan is interested in hearing about any fresh flights of Little Wood Satyr in the DC area and suburbs after July 1.
Hackberry and Tawny Emperors are flying and can be expected most anywhere hackberry and sugarberry trees are found, especially along watercourses.  Locations along the C&O Canal would be a likely spot.  Second brood Viceroy is emerging; look for it around willows.  Baltimore Checkerspots have been reported in many locations around the state this season, including Montgomery, Frederick and Garrett counties.  Good locations are Little Bennett Regional Park near the Kinglsey Road parking lot and in the fields past the boardwalk at Finzel Swamp.  They’re still pretty fresh. The Bath Co. VA count also logged Diana Fritillary.  Aphrodite Fritillary is freshly on the wing at Big Meadow in the Shenandoah NP.  Atlantis Fritillary, Common Ringlet and Pink-edged Sulphur were abundant last weekend at Spruce Knob Lake WV.
Not reported yet this year but expected any day now are Northern Metalmark in Green Ridge State Forest (fresh brood is emerging in VA and was noted on last week’s Bath Co NABA count), Bronze Copper on the Eastern Shore, and Little Yellow most anywhere on the Coastal Plain or Piedmont.  Last summer’s incursion of Dainty Sulphur isn’t going to repeat, it appears, but observers should look for it in last summer’s locations. Checkered White seems even more scarce than usual this season; perhaps someone will report a second brood sightings in the next couple weeks (mid-July seems to be the beginning for that brood).
2013 Fort Indiantown Gap PA Regal Fritillary and Grassland Tours are Friday July 5, Saturday July 6, Thursday July 11, and Friday July 12.
Feedback on whether you find this weekend forecast of interest would be appreciated.  Please let me know what you find over the weekend so I can share it with others in future weekend forecasts, and I hope to run into you in the field!

Tom is coordinating this year’s annual NABA count for DC and issued the following notice:

>>Tom Stock here. I would like to invite one and all to the District of Columbia 4th of July Butterfly Count at the National Arboretum — which will be held this year on Saturday, August 17 (rain date August 18). The details:

WHEN: Saturday, August 17, 2013 — beginning at 9:00 a.m. and lasting until mid to late afternoon (the Arboretum closes at 5 p.m.), depending on heat and butterfly activity. (The count’s rain date is Sunday, August 18 — if in doubt, contact Tom Stock, email below.) The count will end at 4 p.m. at the latest to allow for a “Tally Rally” to compile a list of our sightings, the location of which will be determined the day of the count. We will either rally on the Arboretum grounds or go off the grounds to a local restaurant.

MEETING PLACE: We will meet at 9:00 a.m. in the parking lot of the Arboretum Visitor Center near the R Street entrance. As one enters from R Street, the lot is to the left. Based on the number of participants, we may carpool from there to other locations. 

WHO: ALL ARE WELCOME. No experience is necessary. All are invited to come out and have fun while contributing to butterfly study and conservation. One caveat: the count is not recommended for small children (under age 10-12) given the expected heat, lots of sun and bugs, and tall, brambly vegetation.  I would encourage you to count for at least a couple of hours, but you don’t need to commit to a full day. 

WHERE: We will be counting within the grounds of the Arboretum, which encompasses a wide variety of habitats — from open field to forest to cultivated gardens.

EQUIPMENT: Wear comfortable field clothing, remembering the seasonal realities of a hot sun in open meadows, poison ivy, ticks, and the possibility of biting insects. We will be doing a lot of walking on well cleared paths and roadways, but there may be some “bush whacking” through high grass with lots of brambles, poison ivy, and even very nasty mile-a-minute. So long pants and comfortable walking shoes are encouraged. Also be sure to wear or bring sun screen, insect repellent, and a hat.  Bring lots of water (and Gatorade), and lunch. There are restrooms located at a few strategic locations around the Arboretum.  Close focus binoculars are very helpful, and we encourage you to bring cameras. There will be plenty of plants — if not butterflies — to photograph, though priority will be on counting butterflies rather than on waiting for photographers to shoot. I will have butterfly field guides, but bring one if you have one. 

COUNTING FEE: $3 for ages 12 and older. This fee is passed along to the North American Butterfly Association (NABA) to cover the costs of coordinating the counts and compiling the data. You may also sign up to receive a copy of NABA’s 2013 July 4th Count national report ($7 for members, $10 for non-members).

CONTACT INFORMATION: If you plan to participate or have any questions, feel free to get in touch with me, Tom Stock, at altomomatic |AT| Verizon |DOT| net.<<
