Today’s WABC Event Summary

More than 20 lep enthusiasts came this morning to the Black Hill Visitor Center to hear Denise Gibb and Barbara Kreilly tell us about the Montgomery County reintroduction project for Baltimore checkerspot.  Most of the attendees followed the lecture with a visit to the rearing area and stopped off at the Black Hill native plant sale; a dozen of the hardiest souls joined Tom Stock and Rick Borchelt at Hoyle’s Mill Conservation Park for a post-lunch foray.

Tom and Rick had scouted the area while the main crowd went to the checkerspot rearing area, and the trail through Hoyle’s Mill was quite productive at midday.  The biggest surprises were a dozen or more question marks, fresh and in their second-brood, dark hindwing summer form.  We picked up only a single Eastern comma during the day, and it was a tattered individual winter form.  Juvenal’s duskywings were faded but still common; we saw two fresh Horace’s duskywings during the day as well.  Grass skippers were well represented with Zabulon, Peck’s, and Sachem all in flight, as were least skippers and common checkered-skipper.

We did not, however, find giant swallowtail, although we studied the host plant well — northern prickly ash.  Other swallowtails were in flight:  pipevine, spicebush, and zebra.

The high count of six olive hairstreaks were associated with the abundant Eastern red-cedar in the park.

In all, we picked up 21 species today, including a steady stream of red admirals that have been reported in migration up and down the East coast:
