Lithacodes fasciola, the yellow-shouldered slug or ochre-winged hag moth, is a moth of the family Limacodidae.
Life cycle
There is one generation a year in the north, but two or more in southern USA, so that mature caterpillars may be found from May to November (Wagner, 2005).
Larva
The larva is flattened and ovoid in outline, with a short, squared off 'tail.' Bright yellow-green with yellow and green stripes along its length. Small craters dot the topside. Maximum length 15 mm. Like all limacodids, the legs are shortened and the prolegs are reduced to suction cups. Wagner (2005) notes that a high proportion of larvae have parasitoids. Their presence can be determined before emergence by a black spot formed by the breathing siphon of the fly.
