Rhinostomus

The bearded weevil (Rhinostomus barbirostris) is a species with an interesting sexual polymorphism. A proportion of males in each population is smaller than other individuals of this sex, and resembles females in their appearance. This allows them to sneak unnoticed past the larger males and approach the female without being challenged (Costa Rica). [Canon 1Ds MkII, Canon 180mm macro]
