Exyra semicrocea (Guenée, 1852)
Xanthoptera semicrocea Guenée, 1852
* phylogenetic sequence #931189

Adult - typical form has basal half of forewing bright yellow, distal half dark gray, divided by straight median line at right-angles to costa; some individuals have completely pale yellow forewing except for faint subterminal line; hindwing typically dark gray but may be almost white in pale forms; fringe color varies from black to almost white; top of head and collar black; top of thorax yellow.

Larvae feed on various pitcherplants (Sarracenia spp.), specifically Hooded Pitcherplant (S. minor), S. psittacina, S. sledgei, S. drummondii, S. rubra, and S. flava. When feeding on S. flava, it is usually replaced by Exyra ridingsii that may occur in the area.
