Xanthorhoe labradorensis Packard 1867

Adults in Alberta from late May through late August.

Widespread. Occurs across Canada from NL to BC and AK, north to YT and NWT, south in the east at least LA and MS. Found in open wooded areas, edges etc.

"A small (approximately 2.5 cm wingspan) flimsy moth with a small body and broad wings. Wings light grey., slightly mottled. Basal are red brown, antemedian line prominent, black. Area between antemedian and postmedian lines rust-red, and a small red-brown patch on the costa before the apex. Hindwings light grey. The black antemedian line followed by the wide red median band should separate labradorensis from all but X. packardata McD. These two species are frequently misidentified in collections and elsewhere, and should be dissected for positive identification. In packardata the aedeagus is very slender (about 1/5 as wide as the space within the genital ring (tegument and vinculum) with a peculiar cluster of about 10 setae at the top of the aedeagus that are like cylinders with a thin seta at the tip, like dynamite with a short fuse, and the apex of the valve is flat with a small dorsal process. In labradorensis, the aedeagus is about ½ as wide as the capsule space, there is a large cluster of long tapered cornuti at the top, and the subapical process is larger and projects on the inner surface of the valve as a triangular subapical tooth (D. Lafontaine, pers. comm.)."

Found in open wooded areas, edges etc.

There is a single annual brood, with adults in Alberta from late May through late August. Adults are nocturnal and come to light. The larvae are polyphagus with a range of mostly herbs but also some woody plants listed as hosts (Covell, 1984).

Xanthorhoe labradorensis, the Labrador carpet moth, is a moth of the family Geometridae. The species was first described by Alpheus Spring Packard in 1867. It is found across Canada from Newfoundland and Labrador to British Columbia and Alaska, north to Yukon and the Northwest Territories, south in the east to Louisiana and Mississippi. The habitat consists of open wooded areas and edges.

The wingspan is about 25 mm. The wings are light grey and slightly mottled. The basal area is red brown and the black antemedian line is prominent. The area between the antemedian and postmedian lines is rust red and there is a small red-brown patch on the costa before the apex. The hindwings are light grey. There is one generation per year with adults on wing from late May to late August in the northern part of the range.

The larvae feed are polyphagous and feed on a wide range of plants, including herbs and woody plants.
