Extreme natural size variation in both sexes of a sexually cannibalistic mantidfly

Laurel Lietzenmayer, Lauren Goldstein, Josephine Pasche & Lisa Taylor
In sexually cannibalistic animals, the relative sizes of potential mates often predict the outcome of aggressive encounters. Mantidflies are spider egg predators as larvae and generalist predators as adults. Unlike most cannibalistic species, individual mantidflies can be substantially larger than other individuals, regardless of sex. Using preserved collections of Dicromantispa sayi, we focused on three body size metrics that we found to be positively correlated and accurately measured across researchers. We found extreme size variation...
