Late instar caterpillar reared from eggs obtained September 20, 2009 from adult captured at BL in a willow wetland. Reared on unidentified sedges. This image taken April 15, 2010 (eggs overwinter). The larva was dying of causes unknown, as has been usual for my late-instar rearings of this species from eggs.
