The photos at bottom left and right are of the same specimen.

Enargia decolor is one of three species of Enargia known to occur in the Ottawa area, two of which are illustrated on this web site.

The forewing of Enargia decolor is yellowish overlain with light reddish brown.  The antemedial and postmedial lines are clearly marked in brown, and there is a fairly sharp bend in the am line.  Orbicular and reniform spots are clear yellowish tan, outlined in brown.  The median line is expressed as a brown shade, with a sharp bend near the lower end of the reniform spot.  The wingspan is 30 to 40 mm.

Enargia decolor is very similar to Enargia infumata (Hodges 9550, illustrated on this site), with the most noticeable difference being the presence of a dark spot at the lower end of the reniform spot in Enargia infumata.  Enargia mephisto has also been recorded in the Ottawa area, and has forewings with a more grayish color.

The larvae of Enargia decolor feed on poplar, and bind two leaves together for shelter, giving rise to the common name of Aspen Two-Leaf Tier.  Handfield (1999) indicates an adult flight season in my general area from early August to late September.

I have photographed this species in 2001, on 15 August and on 8 September; in 2003, on 5 and 25 August.
