|scientific name Greya variata |
Meadows and forest egdes with abundant herbs.
Alberta records of adults are from late June to mid-July (Davis et al. 1992).
Relatively small for Greya; lack of specimens makes sexual dimorphism uncertain (Pellmyr 2000). Wingspan 11-13 mm, forewings with dark brown base and two tan patches from hind-margin to near costal margin; hindwing slightly larger than forewing and without pattern (Pellmyr 2000). Head white with brown, antennae 28-30 segmented, 0.6 times as long as the forewing, and dark and pubescent. Maxillary palpus light brown with apical segment approximately twice the length of third, labial palpus white with brown (Davis et al. 1992). Thorax brown dorsally, venter white; legs usually with ventral surfaces white and dorsal surfaces brownish (Davis et al. 1992). Abdomen brownish dorsally, grayish white ventrally (Davis et al. 1992). Apex of female ovipositor compressed, acute; male with uncus superficially bilobed; valva broad from base to pollex; pollex prominent (Pellmyr 2000).
The immature stages unknown.
The larval host plant unknown, but may be Osmorhiza occidentalis (Umbelliferae) (Pellmyr 2000).
Known only from the type locality, Waterton Lakes, Alberta at elevations of 1200-1400 m (Pellmyr 2000).
