The termen is steeply angled creating an apex that is nearly falcate in some individuals. Hindwings are primarily white. Males have a forewing costal fold. Xenotemna pallorana is similar but can be distinguished from C. clemensiana by the lack of a forewing costal fold, a rounded termen on the forewing, and brownish or shaded hindwings. Genitalia of these two species are different and a dissection can be used to confirm identity. Larval Morphology Late instar larvae are approximately 10 mm in length. The head and prothoracic shield are yellowish brown. Pinacula are large and conspicuous. An anal comb is present. Biology Clepsis clemensiana completes one or two annual generations. Adults are present in June and July and again in September for the second generation. Larvae feed on leaves of the host plants. Pupation occurs in a silk tube. Host plants Grasses (Poaceae) are considered to be the primary host for Clepsis clemensiana, although the larvae have been reported feeding on plants in several other families.
