Botys unifascialis Packard, 1873 Explanation of Names UNIFASCIALIS: from the Latin "unis" (one) + "fascia" (band); refers to the whitish band across the forewing, and is the origin of the suggested common name One-banded Pyrausta Numbers Four subspecies: P. u. arizonensis, rindgei, subolivalis, unifascialis Size Powell & Opler (2009) listed the forewing length 10-14 mm. (1)Identification Adult: forewing brown with scattered black scales and whitish S-shaped band across subterminal area; diffuse white discal spot or patch, and partial pale terminal band that fades before reaching apex; hindwing dark gray with large white triangular discal patch; snout, head, and collar with orangish scales.
Powell & Opler (2009) stated "Populations in the north tend to have darker individuals, while those in southern California are paler" (1)
Packard (1873) original description is available online. 261. Range California (2) and Arizona (3) to Yukon (4), east across Canada (5) to Nova Scotia, south in the east to New Jersey and Illinois (absent from southcentral and southeastern states) Habitat Forest openings, clearings, fields were foodplant grows. Season Powell & Opler (2009) reported the flight period as April to August. (1)Food Polyphagous (1)...larvae have been reported feeding on plants in a number of genera/families: pussytoes ( Antennaria, Asteraceae), beans ( Phaseolus, Fabaceae), buckwheats ( Eriogonum, Polygonaceae), and ground-smoke ( Gayophytum, Onagraceae) See Also Other similar species of Pyrausta and Loxostege lack the S-shaped whitish band in subterminal area (see images of related species.
