Lake Artemesia in College Park, Prince Georges Co., is shaping up to be a fine butterfly habitat. As many of you know, it was formed (out of a series of commercial goldfish ponds) from the excavation of soil for the nearby Greenbelt Metro Station, and is easily accessible by car and bike trail. The Lake too (actually two lakes) are bounded by handicapped accessible, paved pathways as well.
Currently in bloom is a great stand of hairy vetch, and smaller patches of common vetch. Dogbane is just coming into bloom, and blackberry is past peak. The lake margins usually hold a fair amount of pickerel weed, just beginning to bloom, which hosts some Broad-winged Skippers later in the season.
I stopped at Artemesia late on Sunday (around 5:30 pm), too late for good butterflying but good birding with a few butterflies thrown in. Leps did include FOY Monarch and its mimic, Viceroy. The afternoon list:
