Synonyms and other taxonomic changes
Xanthorhoe packardata McDunnough, 1945
Identification
Adult: A flimsy moth with a small body and broad wings. FW light grey, slightly mottled. Basal area is red brown, with prominent black AM. Median area, between AM and PM, is rust-red, with a small red-brown and black patch on the costa, before the apex. HW light grey. (1)
in males - antennae simple, ciliate. male antennae in X. labradorensis are doubly bifasciculate (each segment with 2 pairs of setal bundles)


Inward-pointing sharp tooth present in X. packardata (circled in red)
Range
Quebec west to BC. (1)
Habitat
Little is known as to habitat and host plants, but likely very similar to that of X. Labradorensis(1)
Remarks
Black AM followed by the wide red median band should separate labradorensis from all but X. packardata. Xanthorhoe are one of the most difficult groups of geometrid moths to identify, and little has been published on North American members of this genus to date. These two species are frequently misidentified in collections and elsewhere, and should be dissected for positive identification. (1)
