|scientific name Rivula propinqualis |
common name Spotted Grass Moth, Yellow Snout-moth
Clearings, meadows, edges and lush grassy areas.
Adults are on the wing July to mid-August.
A small (1.5-1.9 cm wingspan) broad-winged light yellow or pale tan moth, with the median line forming a wide, elliptical brown patch near the costa, covering two small purple reniform dots. The fine, dark brown antemedian and postmedian lines swing out toward the apex in parallel. The terminal area and fringe shade to dark brown, and there are scattered dark scales over the remainder of the forewings. The hindwings are only slightly paler than the forewing ground, darker shaded toward the margin, and with a faint median line. The antennae are simple and both of the sexes are similar. It is not likely to be mistaken for any other moth.
Adults are nocturnal and come to light and to sugar baits.
A widespread species, no concerns.
No Alberta data; elsewhere reported as either unknown, or as using grasses (Covell, 1982).
Across southern Canada, from Nova Scotia west to Vancouver Island; south to Texas and Georgia. In Alberta, it apparently occurs throughout much of the Boreal Forest region, north to Zama Lake, south in the riparian cottonwood groves along the Red Deer River at Dinosaur Provincial Park.
