Length 17-22 mm.Is easily distinguished from scrutator, of which it has an almost similar color, for its smaller size and for the male's mesotibiae only weakly arcuated, without the brush of red hair on the apex.
It occurs from southern Canada to Texas, but does not penetrate into Mexico.

Material examined:
United States: Texas (Brazos county); Nebraska (Namaha county, Sarpy county); New York (Suffolk county); Missouri (Columbia); Maryland (Allegany county); Illinois (Peoria)

Notes: Winged, diurnal as well nocturnal and attracted to light at night. Adults in great number were observed while feeding upon species of Geometrid caterpillar. Active individuals were captured from April to June (on the basis of the material examined), that is also the coupling period, or all year round according to Erwin (2007: 107), but adults sometime are found overwintering in small cavities in the ground.
