carpenterworm moths
Acossus is a genus of carpenterworm moths in the family Cossidae, established by Dyar in 1905. The genus includes at least six described species, most associated with Populus species as larval hosts. A recently described species, A. boreocryptus, exhibits exceptional diurnal flight behavior, the first documented case among New World Cossidae. Species are distributed across northern North America and northern Eurasia.
