scientific name    Anerastia lotella    

common name     “Rödgrått gräsrotmott” in Sweden.

Primarily native grasslands.

June and July.

A medium-sized Pyralid, with narrow, brown forewings, having a wingspan of 19-27 mm, and light grayish-fuscous hindwings. The costal region of the FW is similar in color to the remainder of the wing, rather than being pale or white as in Peoria approximella, Coenochroa illibella or species of Pima. The genitalia are described by Shafer (1968). Similar to the species of Bandera but somewhat larger and with the frons rounded, rather than being conical.

life history
Univoltine. The larvae are known to feed on the base of the stem and in the root-stock of various grasses (Shafer 1968) as do those of “sod webworm” Crambids. Pupates in a silken cocoon near the larval tube (Goater 1986). Adults rest on grass stems during the day, are active at night and come to light.

Never common, but probably of no concern.

diet info
The local food plants are unknown but may include species of Festuca.

A European and New World species, which occurs in North America from Alaska and the Northwest Territories south to Washington, east to Quebec and Minnesota (Shafer 1968). In Alberta, reported from Area 10 (Edmonton) by Bowman (1951).
