Pyrrhia adela (formerly Pyrrhia umbra), sometimes called the Bordered Sallow, is one of two species of Pyrrhia known to occur in the Ottawa area (J. D. Lafontaine, pers. comm., 2001).

The forewing of Pyrrhia adela is predominantly orange.  The basal, antemedial and postmedial lines are reddish brown, as are the outlines of the orbicular and reniform spots.  Some of the veins are also marked in reddish brown.  A reddish brown medial line crosses the wing between the orbicular and reniform spots.  The lower end of the reniform spot is partly filled with a reddish color.  There is also brown shading between the postmedial line and a scalloped subterminal line.  The hindwing is yellowish, with a band of reddish brown along the outer margin, sometimes with grayish shading overlying the reddish-brown.  Covell (1984) indicates a wingspan of 3.2 to 4.0 cm for this species.

According to Handfield (1999), the larvae of Pyrrhia adela have been reported to feed on rose, sumac, black walnut and several other plants. He indicates an adult flight season from the beginning of June to nearly mid-July for my general area.

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