Acsala is a monotypic genus of lichen moth in the monotypic subtribe Acsalina of the family Erebidae. Its single species, Acsala anomala, has Hodges number 8104.1[1] and is known from the US (Alaska) and Canada (Yukon).[2]

Behavior

Eggs are deposited in a single layer on the underside of rocks, in batches of up to thirty, and take eight to ten days to hatch.[3] Larvae feed on rock-growing lichens, with a strong preference for black foliose and crustose lichens.[3] Species of Buellia, Lecidea, Orphniospora, Parmelia and Umbilicaria have been recorded as food sources.[2][3]

Adult males possess weak flight and are day-active; females are flightless and spend much of their time under rocks.[3]

Appearance

Freshly laid eggs are red-orange, and later turn pale orange.[3] Larvae have barbed setae.[3] Adult males have broad wings with a wingspan of 27–28 mm, while adult females possess narrow (Template:In") wings.[2] Wing venation is variable.[3]

Taxonomy

Acsala anomala and its genus were both first described by Foster H. Benjamin in 1935.[4][5] Subtribe Acsalina was introduced in 1983 by Franclemont, but remained a nomen nudum until a formal description was given in 1999 by Amel Bendib and Joël Minet.[2]
