Synonyms and other taxonomic changes
Lycomorpha pholus (Drury)
Orig. Comb: Sphinx pholus Drury, 1773
Syn: Phalaena pholus (Drury)
* phylogenetic sequence #930201
Wingspan 25-32 mm (Scott, 2010); body length about 10 mm.
Forewing length 12-15 mm. (1)
Adult - body and wings bluish-black. Basal portion of wings yellow, orange, or red; distal portion of wings black. Amount of yellow/orange/red varies, according to published photos and illustrations.
Larva - gray dotted with pale green, sparse long hairs, resemble those of Hypoprepia (Forbes, 1960; Dyar, 1897).
Eastern North America to the Rockies, Alberta south to New Mexico - Map (1)
Mostly: June-Sept (MPG)
Larvae feed on lichens. The strictly diurnal adults are often found on flowers of dogbane (Apocynum, Apocynaceae), goldenbush (Ericameria, Asteraceae) and goldenrod (Solidago, Asteraceae). (1)
Life Cycle
May take several years to develop, especially in the north. Hairy cocoons are attached to rocks or tree trunks near the former food source.
Central North American specimens are subspecies Lycomorpha pholus miniata and show red on the wings; eastern specimens of the nominate race have the red replaced by yellow (paraphrase of Gerald Fauske, Moths of North Dakota).
The red color pattern is thought to be mimicry of poisonous Lycid beetles, such as Calopteron.
Another possibility is the Elderberry Borer.
