Agriphila attenuata    



habitat
Native grassland.

seasonality
Late August to early September.

identification
A larger crambid (24-26 mm wingspan) with conspicuous, brushy, porrect labial palps and narrow forewings (as the species name implies). The forewings are pale cinereous with fuscous areas and a scattering of dark scales. A poorly defined, whitish stripe extends from the base to the terminal line. It is crossed beyond the cell by an oblique dark line. The terminal space is narrow, light yellow-orange in color with seven dark dots. The space, subterminal and terminal lines parallel the termen except near the apex where they run obliquely into the costa. The fringes are whitish in color. The hindwings are pale fuscous, somewhat darker than the forewings. The genitalia have apparently not been illustrated. Originally described as Crambus attenuatus (Grote 1880).

life history
Unknown. Adults fly at night and come to light.

conservation
Probably of no concern.

diet info
Unknown. It is likely that the larvae feed on grasses.

range
A western North American species. Described by Grote (1880) from a specimen collected on Vancouver Island by Henry Edwards. In addition, Fernald (1896) reported it from California and Columbia (sic). Listed from many Counties in the online California Moth Specimen Database. Clifford Ferris (pers. comm.) has found it in Albany Co., Wyoming. A male genitalic preparation which Ferris prepared matched that of Alberta material. Not reported for Alberta by Bowman (1951) and unknown in the Province until now. In Alberta, known mainly from areas along the Battle, Red Deer, South Saskatchewan and Lost Rivers. An interesting exception was a collection from a mixedwood area, 8 km NW of Winfield.
