Eupsilia devia is one of four species of Eupsilia that have been recorded from the Ottawa area (J.D. Lafontaine, pers.comm., 2001).

Eupsilia devia has a gray and brown forewing with fairly well defined markings.  The entire basal area is quite frosted with white, with a fairly distinct curved whitish basal line.  Following the more or less straight antemedial line, the median and subterminal areas are predominantly brown.  The orbicular spot is not evident, but the whitish outline of the reniform spot is fairly complete, filled with brown and with a darker spot in the filling at the lower end.  The thin whitish postmedial line has a slight smooth outward curve.  The subterminal line is less smooth but also curves slightly outward.  Between these two lines is another heavier whitish line that is fairly straight and actually crosses the st line to reach the costa at a point close to the apex.  The fringe is gray-brown.  The hindwing is also gray-brown.  According to Covell (1984), the wingspan ranges from 3.0 to 3.5 cm.

The larvae of Eupsilia devia feed on aster, goldenrod and cherry, and also oak and poplar (Handfield, 1999).  According to Handfield, this species overwinters as an adult, with flight seasons in my general area from early April to the later part of May, and from late September to late October.

My records to date for Eupsilia devia (each date representing "the night of") are in the table below:
