Catocala coccinata
Scarlet Underwing
Catocala coccinata is a large underwing moth in the family Erebidae, first described by Augustus Radcliffe Grote in 1872. Adults are characterized by cryptic forewings that conceal brightly colored hindwings, which are exposed when the moth is disturbed. The species occurs across eastern North America, with larvae specializing on oak species. Two subspecies are recognized: the nominate form and C. c. sinuosa from Florida.
