|scientific name Oligocentria pallida |
common name Pale Prominent
Dry deciduous and mixedwood woodland.
The only Alberta specimen was collected in early August.
A medium-large (4.6-4.8 cm wingspan), pale rusty brown and tan moth, with few markings. Markings on the forewings consist of a thin dark vertical line at the end of the cell and some dark rust or maroon along the wing base and the anal angle. The outer two-thirds of the costa is grey, with a pair of short, parallel horizontal streaks near the apex. The hindwings are pale yellow or tan (male) or grey (female) with a dark patch marking the anal angle. Sexes similar, but females larger and darker. Other species of Alberta Oligocentria lack the prominent rusty-red coloring of pallida.
Poorly known. Larvae are solitary defoliators, and there is a single annual brood. Adults come to light.
Barely reaches extreme southwest Alberta; known in AB from a single collection.
No Alberta data; elsewhere reported to feed on willow (Salix), apple (Malus), maple (Acer) and poplar (Populus) (Miller and Hammond, 2000.); also rose (Rosa) and saskatoon (Amelanchier) (Jones, 1951).
The mountains of extreme southwestern Alberta, west to Vancouver Island; southward.
