|scientific name Narraga fimetaria |
The only available Alberta date is July 12.
A small geometrid with unique markings and strongly pectinate antennae. The upper side is dark yellow-brown with a short, beige subapical band and checkered wing fringes. The underside is beige with silvery white markings, reminiscent of a miniature fritillary butterfly.
The immature stages are undescribed. The closely related N. georgiana feeds on shrub goldenrod (Chrysoma pauciflosculosa), and fimetaria may feed on a similar species of composite. Adults are likely diurnal like those of georgiana (Covell et al. 1984), but they do come to light at least occasionally. This species may be double-brooded in Alberta, flying in May and again in July-August, as is the case for other members of the genus (Covell et al 1984).
The only Canadian records are for two specimens collected in Alberta.
Unknown. A closely related species feeds on shrub goldenrod.
Southern Alberta south to Texas and California. In Canada, known only from Lethbridge (McGuffin 1972) and Dinosaur Provincial Park.
