foundresses collected in Ithaca, New York,
representing some of the diversity in facial patterns. The central wasp has no black
clypeus pigmentation, the remaining wasps have one to three spots. In 158 randomly
collected foundresses, 19.6% of foundresses had an entirely yellow clypeus, 65.8%
had a single black spot, 12.7% had two spots and 1.9% had three spots. On average,
13% of a wasp's clypeus was pigmented black; this value ranged broadly from 0 to
39%. Photos © Elizabeth Tibbetts.
