My god, this must be my least favorite moth genus. It looks like someone left the copier on and accidentally made thirteen bad copies. At least the moths have some color, which cannot be said of the caterpillars. Boring green worms. Jamaicensis is a common species throughout a large part of the United States and Canada, only absent from the very extreme north of Canada and the southern half of western California. The wingspan is quite variable between four and a half and eight centimeter. In captivity they tend to be on the smaller side of the spectrum, especially when reared warm in which case there is a rapid succession of generations. Wild populations have one (in the north) to three (in the south) flights. In the warmer parts of its distribution jamaicensis flies from February until October. The further north the later they emerge.
