Identification
Members of the Eudioctria are among the smallest North at 6–8 mm in length. They superficially resemble Cerotainia but lack the extra-long characteristic of that genus. Eudioctria propinqua is distinguished from other Eudioctria species by examination of facial gibbosities and the degree of pollinosity on body parts. Behaviorally, Eudioctria prefers perching on flat leaves at the top of small shrubs, unlike Cerotainia which tends to perch on twig-ends.
Distribution
Eastern North America; occurs in the eastern United States alongside three other Eudioctria (E. albius, E. brevis, and E. tibialis). The Eudioctria is primarily western in distribution, with only four of its fourteen species occurring in eastern states.
Behavior
Perches on flat leaves at the top of small shrubs.
