According to Cretekos et. al., a bat-specific prx1 enhancer region could be the reason these structures exist in bats.

A controversial study by Nudds and Dyke in 2010 posited that A. lithographica could not fully use these structures. After metamorphosis, butterflies must engorge these with hemolymph. Dragonflies are one of only insects to have muscles directly powering these structures. Convergent evolution explains the presence of these structures in both insects and bats, in which these structures are homologous to bones in the limbs of other mammals. Name this appendage, commonly possessed by birds and other animals that can fly.
