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
Four subspecies: P. u. arizonensis, rindgei, subolivalis, unifascialis
Powell & Opler (2009) listed the forewing length 10-14 mm. (1)
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.
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)
Forest openings, clearings, fields were foodplant grows.
Powell & Opler (2009) reported the flight period as April to August. (1)
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)

Other similar species of Pyrausta and Loxostege lack the S-shaped whitish band in subterminal area (see images of related species.
