|scientific name Protoperigea anotha |
common name Kaslo Rustic
In Alberta it has been collected only in montane grasslands.
Flies in mid-late summer.
A pale and somewhat silky light yellowish-grey moth. Darker markings include a somewhat erratic antemedian line and a toothed curving postmedian line, both with black blotches where they meet the costa, and a large reniform spot, all rather blurred and poorly defined. The subterminal area is slightly darker than the rest of the forewing, and the fringe is concolorous . The hindwings are very pale grey-brown, almost white. A non-descript moth with a rather delicate build. The cloudy pattern and silky sheen of Protoperigea species is difficult to describe but quite distinctive. They are similar in this regard to Pronoctua species, which are larger, darker and browner. The larger and browner P. posticata replaces anotha in the dry grasslands and badlands of southern Alberta.
Poorly known. There is a single annual brood, which flies in mid-late summer. The adults are nocturnal and are attracted to light.
A western species, occurring from the mountains of western Alberta north to Jasper, west to Lilloet BC and south to California. In Alberta it has been collected only in montane grasslands, from the Crowsnest Pass north to Jasper.
Little is known about this rather nondescript moth. It is a western species, barely entering Alberta at low elevations in the mountains. Until very recently there were only 2 Bowman specimen records from the first half of the last century. In 2005 and 2006 we found it at both Jasper National Park and Kootenay Plains.
