Sideridis rosea, sometimes called The Rosewing, is one of several species of Sideridis recorded from the Ottawa area (J.D. Lafontaine, pers. comm., 2001).

The forewing of Sideridis rosea is light reddish brown, with darker reddish brown markings.  The dark brown basal and antemedial lines are well defined and somewhat sinous.  There is a somewhat wider, dark reddish brown medial line crossing the wing and just skimming the inner side of the reniform spot.  The postmedial line has sharp outward points separating its scallops.  Beyond the postmedial line, there is a dark reddish brown shade immediately preceding a somewhat irregular pale subterminal line.  The area between the st line and the outer margin is also shaded with reddish brown.  The orbicular, claviform and reniform spots are outlined in brown, and there is a blackish mark inside the lower end of the reniform spot.  The hindwing is whitish beige, with a somewhat irregular grayish line preceding some light gray-brown shading along the outer margin.  The head and thorax are reddish-brown.  According to Covell (1984), this species has a wingspan ranging from 3.5 to 4.5 cm.

Handfield (1999) indicates that the main host plants for Sideridis rosea are reported to be gooseberry, soapberry and willow.  For my general area, he indicates an adult flight season from just after mid-May to about mid-July.

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