Identification
Eudioctria are among the tiniest North at 6–8 mm length. They superficially resemble Cerotainia species ( Laphriinae) but lack the extra-long characteristic of that . Species-level identification requires examination of facial gibbosities and assessment of pollinosity on various body parts.
Distribution
Eudioctria dissimilis occurs in eastern North America. The Eudioctria is primarily western in distribution, with four of its 14 —albius, brevis, propinqua, and dissimilis—occurring in eastern states.
Behavior
According to Norman Lavers, Eudioctria preferentially perch on flat leaves at the top of small shrubs, a behavioral distinction from the related Cerotainia, which tends to perch on twig-ends.
