Pheosia rimosa

Description

Pheosia rimosa, the black-rimmed prominent moth, fissured prominent or false-sphinx, is a species of moth of the family Notodontidae. It is found from coast to coast in North America, although it is less common in the south-eastern United States. The wingspan is 43–62 mm. Adults are dark black-brown and white. The forewings are white with a dark strip along the costa and along the entire lower margin. The hindwings are white with a dark blotch in the anal angle. Adults are on wing from spring to fall. The larvae feed on the leaves of Populus and Salix species. They resemble young hornworm larvae of the family Sphingidae. The colour is variable and can be yellow, lavender, pink, green, brown or nearly black. Full-grown larvae can reach a length of about 45 mm. The species overwinters in the pupal stage.
