|scientific name Euxoa sinelinea |
Open boreal woodland on sand.
Adults have been collected in Alberta in July.
A medium-size (2.7-3.1 cm wingspan) dark grey-brown moth. Head paler than thorax, and a darker black-brown prothoracic collar. Basal, antemedian and postmedian lines incomplete. Reniform and orbicular usually filled with pale grey scales, with a black basal dash and black scales before the orbicular and filling the space between the orbicular and reniform. Claviform a small black wedge or reduced to a few black scales, the area beyond often with lighter red-brown scaling. Subterminal line finely marked by light grey scales or obsolete. Terminal and subterminal areas brown, fringe concolorous or slightly paler brown. Hindwings lighter grey-brown, paler toward the base; fringe paler grey-brown.
Very similar and closely related to Euxoa divergens, which is larger, browner and has pale scaling along the cubital veins. Sinelinea is also a member of the subgenus Longivesica, characterized by the very long vesica in males and long appendix bursae in females. The male valve is narrower subapically in sinelinea, and the appendix bursa in females is shorter in comparison to divergens.
Poorly known. There is a single brood each year, and adults come to both light and sugar baits.
Uncommon but widespread; no concerns.
Unknown. Probably a variety of low plants as in other members of the genus.
Labrador west to eastern Alberta, south to Michigan and central Alberta In Alberta, found throughout much of the boreal forest along the eastern side of the province, from Redwater north to Lake Athabasca.
