Larva
Body light green with short light hairs, at maturity with three brilliant wine-red longitudinal stripes, head and prothoracic plate yellow.
Biology
The larvae feed on Dichanthelium clandestinum. They mine the leaves of their host plant. The mine is an irregular longitudinal blotch mine with the frass ejected at one end. At maturity the larva cuts a circular piece out of the epidermis of its mine, which it bends lengthwise and uses for a cocoon exactly like the genus Cycloplasis. There are two generations, the adults have emerged from late May to early June and again in late July and August. The specimens from Michigan are obviously from the second generation, the mines were collected in August and the adults emerged in May.
