Length: 3.0 mm
We have photographed the adults of this species in West Virginia in July, August, and September, and once in February when an adult was found sheltering under bark.
Some publications have used the name Erythroneura aspera for this species.
As with so many of the species in the subfamily Typhlocybinae, so in Erythridula aspera "The male genitalia are distinctive," as Beirne (1956) put it. Other traits such as color and markings can be quite similar to a number of related species.
