|scientific name Cheteoscelis bistriaria |
common name Oblique-striped Emerald
Late June to mid August, possibly double-brooded.
A small to mid sized geometrid with a bright green forewing, crossed by two white lines The hindwing is green only beyond the PM line, and white basally; all other emeralds (Nemoria, Synchlora, Mesothea) have green rather than white hindwing bases.
This species is most closely related to Synchlora among the emeralds, and shares the larval behaviour of attaching flower bits to itself for disguise. The larvae hibernate (Ferguson 1985).
No obvious concerns.
Larvae feed on the flowers of Solidago, Helianthus and Rosa (Ferguson 1985).
Southern BC, Alberta, and Saskatchewan south to TX, AZ and CA (Ferguson 1985).
