Lake Artemesia LepTrek

The assembled gang about to head out on the LepTrek (me behind the camera)

Here’s the gang for today’s LepTrek to Lake Artemesia in College Park, PG Co.  Perfect weather — sunny and warm but not too hot  And a lot of good nectar sources.  From left:  Missy, Eric, Beth, Jane, Lynnete, Dave, and Scott.  I’m holding the camera.

Most of the action was around the planted hedges of glossy abelia on the left side of the lake, which held large numbers of sachem, Eastern tiger swallowtails (including some dark forms), various sulphurs including sleepy orange, and the occasional monarch.  The abelia also yielded most of the day’s count of crossline skippers, as well as a number of Peck’s.  We picked up zabulon skipper several times on the eastern side of the lake complex.

Beth Johnson snapped this one so I could get into the picture!

Dipped, unfortunately, on the broad-winged skippers, even though a good bit of pickerel weed was in flower.  One of the most interesting sights of the day was an intermediate form of female Eastern tiger swallowtail — halfway between light and dark forms.

The list below is our take for the day (although we were frequently split up so not everyone saw the same species).  Abbreviations follow the NABA convention of s=superabundant, a=abundant, c=common.
