description |
A dark, blackish-brown species with two distinctive yellowish marks down the back. The wings are mostly concolorous with the rest of the body, with rufous-tinted tips. Sexes can be distinguished from one another by the length of the horn- in females, the horn is noticeably long and prominent, while in males the horn is much smaller, sometimes nothing more than a little nub. Egg masses are whitish in color, resembling raised shells on a stem.

comments |
Recent studies have shown that there are a number of undescribed species within the Enchenopa binotata species complex, with each undescribed species feeding on a specific, different host plant. These host plants include Cercis (redbud), Juglans (walnut), Viburnum, and Carya (hickory). Adults of the various species cannot be distinguished from one another, so it is imperative to record the host plant that Enchenopa individuals are found on. Some nymphs of this complex are distinctive enough to be identified to species: see here. |
