Catocala
underwing moths, underwings
Catocala is a large Holarctic genus of moths in the family Erebidae, containing over 250 species. Adults are medium to large with cryptic forewings that conceal brightly colored hindwings when at rest. The genus is renowned among collectors for its diversity of hindwing patterns in orange, red, white, blue, or black. The common name "underwings" derives from the habit of hiding the colorful hindwings beneath the dull forewings. The genus name combines Greek words meaning "beautiful below" or "beautiful hindwings."
