Temnostoma barberi
Bare-bellied Falsehorn
Temnostoma barberi is a Nearctic syrphid fly (hoverfly) described by Curran in 1939. The species exhibits Batesian mimicry of hymenopterans, with adults showing behavioral mimicry by moving their forelegs in front of the head to simulate wasp antennae. It is closely related to T. daochus, and both species form a lineage sister to the rest of the genus Temnostoma. The species has a strikingly different mimicry pattern compared to T. daochus, contributing to understanding of evolutionary plasticity in wasp mimicry.
