» Genus Labiobaetis (Tiny Blue-Winged Olives)
6 species aren't included.
The species of this genus can be identified by the combination of its tiny elliptical hindwings lacking costal projections (
Costal projection: A bump or point sticking up from the front margin of an insect's wing, usually the rear wing of certain mayflies. It is sometimes called a costal process.) ( a few obscure species have them but they are so reduced as to be barely observable under low magnification) and lacking a conical mesonotal projection (Conical mesonotal projection: small cone shaped spike sticking up from the top and front part of the middle thorax segment.). Their two tailed nymphs are more difficult.
