Abstract

Celastrina humulus (new species) is named and compared to related and sympatric Celastrina. It is univoltine, and usually sympatric with the univoltine Celastrina ladon sidara and barely overlaps the end of the sidara flight, as adults emerge from post-diapause pupae later than sidara. It has a different habitat, and a different host (most populations feed on male flowers of hop Humulus lupulus, but one set of populations feeds on Lupinus argenteus flower buds). Adults are whiter than sidara. Adults are electrophoretically most similar to the eastern Prunus serotina gall feeding host race, and are somewhat similar to eastern neglecta. 1st-stage larval setae differ slightly from C. ladon sidara, mature larvae are variable but differ slightly in the frequency of color forms, and pupae differ somewhat in color, and in size of black spots.
