Citheronia laocoon

The moths are relatively large, with a 130-mm wingspan. They do not have a prominent discal spot, neither on fore or hindwing. Females are yellowish black, with orange-red venation. Males look similar, however they are smaller at 110-115-mm wingspan on average. The venation is more vivid and pronounced, however. Their hindwings are highly variable, ranging from yellow with a brown band to mostly red with yellow patches and brown stripes. Their abdomen are yellow, with a red dorsal side and sometimes have red flecks on the side. Caterpillars are quite large, as with many others in the Citheronia genus, and are prominently green, with long prolegs that sport black 'racing stripes' and red 'horns' along each segment of their body. They also have an alternating pattern of a black stripe on each segment, that terminates at the spiracle (arthropods). Their dorsal side is darker green than their ventral side.
