Sicya Guenée, 1857
6 species in North America (
2 species in Canada (CBIF)
all of Canada, including the arctic, northeastern US, and western US through Arizona and California to Mexico and at least as far south as Costa Rica (absent from Texas, Florida, [and the Gulf states?])
Some of the species IDs may not be reliable from just a photo, since a few of them look nearly identical and each may be slightly variable. (Bob Biagi)
(for example): A species level match could not be made, the specimen is likely to be one of the following: Sicya crocearia matches at 100%, Sicya macularia at 99.9%
