|scientific name Pangrapta decoralis |
common name Decorated Owlet
It frequents wooded areas on sandy or other well-drained soils with blueberry.
A fairly small (wingspan approx. 2.5 cm) light violet-brown and rusty yellow moth with somewhat pointed angular wings. The forewings have a poorly defined antemedian line and more prominent dark thin postmedian line, bordered basally by a relatively wide yellow brown band. Beyond the postmedian line the wing is light violet brown with rusty yellow mottling in the upper half. The narrow dark terminal line is followed by light brown fringe. There are darker patches on the costa just before the apex and over the reniform. The reniform is poorly defined and surrounded by a large patch of rusty yellow. The hindwings are similar in color to the forewings, with the forewing bands and lines continuing across them. The hindwing median area is slightly paler than the remainder of the wing, and contains a prominent angular black spot. The palps are prominent. The antennae are beadlike with short bristles.
Poorly known. There is a single annual brood and the adults are nocturnal and come to light. The larvae feed on blueberry (Vaccinium sp.). The single Alberta specimen was collected in late June.

Widespread in eastern North America, west across the southern boreal forest to eastern Alberta. In Alberta it has been collected at Moose Lake, just southwest of Cold Lake.
Pangrapta decoralis is the sole Alberta representative of the subfamily Eublemminae. It was recently (2005) added to the Alberta list when Bruce Christensen collected a single specimen at Moose Lake Provincial Park.
