A fly-mimicking weevil (Hoplocopturus sp.) from the Ecuadorian rainforest. Most cases of insect mimicry involve the imitation of a toxic or distasteful species as a model, so the reason for this beetle to appear like an entirely edible fly is not immediately apparent. However, entomologists studying these insects suggest that because flies are so agile and quick, most visually-oriented predators (particularly birds) probably learn to avoid wasting their time pursuing them, hence the incentive for this “evasive mimicry”.
