Scientific NameSericosema juturnariaCommon Name
Unknown in Alberta; likely dry, shrubby or open montane slopes.
The single Alberta record is for August 1.
The relatively large size, conspicuously pectinate antennae and unmarked, broadly brown-bordered wings will distinguish this species.
Eggs overwinter, and the grey larvae mimic twigs and rest outstretched (see Miller 1995 for an illustration of the larva). Pupation is in a cocoon underground (McGuffin 1981).
Provincial status uncertain, known from a single specimen in Alberta.
Unknown in AB; larvae feed on Ceanothus sanguineus and Rhamnus sp. elsewhere (McGuffin 1981).
Southern BC and extreme southwestern AB south to California (McGuffin 1981).
