Lacinipolia lorea, sometimes called the Bridled Arches moth, is one of seven species of Lacinipolia that have been recorded from the Ottawa area (J.D. Lafontaine, pers. comm., 2001), of which six are illustrated on this website. My thanks to Dr. J. Donald Lafontaine of Agriculture Canada for confirming my identification of the specimen illustrated at top right.

Lacinipolia lorea has a light yellowish brown forewing with a darker brown median.  The area preceding the antemedial line is light brown; the am line itself is faintly double, scalloped, and defined with dark brown along the outer edge. The orbicular and reniform spots are light yellowish brown, contrasting with the darker brown median; there is a dark gray blotch in the lower end of the reniform spot.  The postmedial line appears as a single fine dark brown line.  The subterminal area is usually pale yellowish brown, but with a darker brown patch at the costa.  A darker brown shade is often evident in the terminal area outside the inconspicuous subterminal line.  The dark brown tracing on the veins is most evident in the subterminal area.  A fine, continuous dark brown terminal line precedes the fringe.  The hindwing is grayish brown with a pale fringe.  Covell (1984) indicates a wingspan of 3.0 to 3.5 cm for this species.

According to Handfield (1999), the larvae of Lacinipolia lorea have been reported to feed on a wide variety of plants, including alfalfa, blueberry, clover, dandelion, birch, strawberry, sweet fern, spiraea, black cherry, pincherry, viburnum, geranium and others. He indicates an adult flight season from early June to the end of July for my general area.
