scientific name    Plagiomimicus spumosum    

habitat
Dry open disturbed areas

seasonality
Adults have been collected in Alberta in late July.

identification
A medium-sized (3.3-4.0 cm wingspan) rather delicate brown moth with few markings. The forewing is dull grey-brown to yellow-brown, with a very faint narrow antemedian line and slightly more prominent postmedian line, and with the basal and in particular the terminal area slightly paler. The hindwings are lighter brown, almost white in the basal half, occasionally with a faint lighter median line. Antennae simple and sexes similar. The related P. expallidus is smaller and more contrastingly marked. Poole (1995) illustrates the adults and the genitalia of both sexes, and provides a key to the species of Plagiomimicus

life history
There is a single annual brood, with adults on the wing in mid-summer. They are nocturnal and are attracted to light. The larvae burrow into the heads of the host and feed on the seeds. The larvae have been described by Crumb, 1965, Forbes, 1954, and Poole, 1995. There is a single annual brood, with adults on the wing in mid-summer. They are nocturnal and are attracted to light.
