The genus Cisthene
includes 20 described species listed for America, north of Mexico.(2)(3)
Pictured Lichen Moth is one of the two species in the genus which has a completely orange thorax, a character shared with Angel Lichen Moth. The basal streak is wide, straight edged, and broadly connected to a wide PM band. The PM band is perpendicular to the inner margin and is usually smoothly concave on both sides (Sexton & McGuinness, 2017.)
Apparently has a limited distribution mainly in the s. Great Plains. Documented from Texas, Oklahoma, Colorado, and s.w. Missouri. There are a few records in s. Indiana which may represent the n.e. limit of the range or strays. A few recent records in Vermont are remarkable. The species seems not to be common anywhere.
Some specimens were collected in riparian woodland corridors within semiarid grasslands or shrublands.
In Texas and Oklahoma, adults have two flight periods, April-May and September-October (iNaturalist, MPG, BG records).
Previously confused with both Angel and Kentucky Lichen Moths.
Angel Lichen Moth
- also has entirely orange thorax (including central disk) but is confined to riparian corridors in arid southwestern habitats. The PM band is oblique and nearly parallel to the outer FW margin. The ranges of the two species barely overlap in s.w. Texas.
Kentucky Lichen Moth
- can look similar but has a dark thoracic disk. Ranges further east.
