Description

C. longicornis is a long-legged, green fly with an iridescent exoskeleton. Like other flies in the Condylostylus genus, it holds its wings diagonally while at rest.^[3] C. longicornis can be differentiated by dark femora, a brown fore tibia, and non-uniform bristles along the mid- and fore-tibiae. Males of the species have a sparse row of bristles along the mid tibia and basitarsus, and females will always have a yellow mid-tibia.^[4][2]

Habitat

C. longicornis generally prefer habitats that are lightly shaded and near swamps, streams, meadows, or woodlands.^[5]
