Figure 2. Anisota peigleri Riotte male moths are smaller than females, the body ranging from 15 to 20 mm in length. The forewings are dark reddish brown with a small white spot and a larger whitish translucent patch. The hindwings are mostly reddish brown. Males have plumose (featherlike) antennae that they use to locate females by tracking the pheromones females release during their "calling."
