Dioctria wilcoxi
Dioctria wilcoxi is a small robber fly (Diptera: Asilidae) described by Adisoemarto and Wood in 1975. It belongs to the genus Dioctria, a group of diminutive predatory flies within the subfamily Stenopogoninae. The species is currently treated as a synonym of Dioctria tenuis. Like other members of this genus, it is among the smallest North American robber flies, measuring approximately 6–8 mm in length. Species in this genus are morphologically similar to Cerotainia but can be distinguished by their shorter antennae and behavioral differences in perching habits.
