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. Nymphs are a distinctive white and black color, with a small forward-facing horn and spines down the middle of the abdomen. See here for a nice depiction of the life cycle of nymphs of this genus.

Habitats and Life History
Habitats: Has been found in grassy, brushy habitat and mixed hardwood, cypress forest.
Plant Associates: Black walnut (Juglans nigra)
Behavior: Can be attracted at night with a light.
Comment: 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), and Viburnum. 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.
