Schinia arcigera is one of five species of Schinia
recorded from the Ottawa area (J.D. Lafontaine, pers. comm., 2001), two of which
I have photographed at my location. Members of the genus Schinia are
often termed the Flower Moths, for their habit of resting, feeding and laying
eggs on the flowers of their food plants (Covell, 1984). My thanks to Dr. J. Donald Lafontaine of Agriculture Canada for confirming my identification of the specimen
illustrated at top left and bottom right and left above, which was collected and given to the Canadian National
Collection in Ottawa.
Schinia arcigera has a brown forewing. The dark
chocolate brown basal area is bounded by a smoothly curved, clear white
antemedial line. The lighter, grayish brown median is crossed by a darker
brown shade against which the dark reniform spot is often difficult to
see. The fairly straight white postmedial line is followed by a dark
chocolate shade extending nearly to the outer margin. The thorax is dark
reddish brown. In the female (which I have not photographed), the hindwing
is dark brown to black with a pale fringe. The male, however, has a yellow
hindwing with a band of black along the outer margin and a black spot in the
yellow area near the center of the wing. Coverll (1984) indicates a
wingspan ranging from 2.2. to 2.5 cm for this species.
According to Handfield (1999), the host plant for Schinia
arcigera is reported to be aster species. For my general area, he indicates an adult flight season from
near the end of July to near the end of August.
