Identification

Adults

Metalectra bigallis is fairly small (FW length 14 mm) mottled dark brown moth with stubby rounded wings with lightly scalloped margins at the base of the fringe. Both forewings and hindwings have mottled dark brown ground color with irregular poorly defined pale lines. The costa and filling of the reniform spot are darker sooty black on the forewing, and the large discal spot and surrounding wing base is similar blackish on the hindwing.
