Ottawa (Dunrobin), ON Canada

Both photos are of the same specimen.  My apologies for the poor quality of the photo on the right; I was still in the process of learning to use a new camera and was having problems with depth of field and focus.

My thanks to Dr. P.T. Dang of the Canadian Forest Service for identifying this species from the actual specimen illustrated above.

Pseudexentera cressoniana is one of five species of Pseudexentera known to occur in the Ottawa area.  Viewed from above at rest with its wings closed, P. cressoniana looks as if it has a pale head and shoulders outlined by the blackish areas on the inner third of the forewing.  I have distinguished this from other similar unidentified species I have photographed by the outward finger of the black area that defines the "shoulder" of this pattern.  The pattern of the outer half of the forewing is complex, in light gray, darker brownish gray and near black.  I estimate the wing length at something less than 10 mm. 

From the results of an Internet search, the larvae of Pseudexentera cressoniana are apparently leaf rollers on hickory.

I have photographed this species in 2003, on 14 and 20 April.
