Adult Markings: The following description is based on Clemens (1859a) and Forbes (1923). The head and thorax are dark ocherous and tinged with reddish, and the head lacks a black spot behind the antenna. The palp is dark brown but yellower on the inner face. The forewings is pale yellowish brown, dusted with black scales, and sometimes suffused with fuscous, which leaves a contrasting yellow inner margin on the basal half. A conspicuous dark brown spot is present on the end of the disc. In addition two smaller spots or blotches of the same hue are sometimes evident between this and the base of the wing. One is about the middle of the disc, and the other beneath it in the submedian fold. The fringes are unicolorous and rather paler than the general hue. The hindwing is dirty white to light tan fringe. |
Wingspan: 15 mm (Forbes, 1923) |

Immatures and Development: Very little is known about the larval life history. The larvae appear to be scavengers or detritivores based on observations made by Clemens (1859a). He found larvae in one of his insect boxes that constructed silk-bound cases out of detached portions of the insects and the scales. The eggs were whitish, smooth and nearly cylindrical, but tapering slightly toward the upper end. The mature larva was of a dirty white color, with a black head and black cervical shield. Two adults emerged, one on 13 March and the other several days later. Nelson (1968) found larvae in wasp nests that appeared to be feeding on the paper nest itself rather than the wasp larvae.
