Nemoria unitaria – (Packard, 1873)
* phyloygenetic sequence #206375
described in 1873 by Packard, who originally placed it in genus Eunemoria
wingspan 25-34 mm, based on several Internet photos
Adult: the largest emerald, its distinguishing feature is on the hindwing, where the AM and PM lines join to form a single U-shaped loop; however, in many northern specimens, the line may be so weak that a loop is not distinguishable, leaving a single curved line - as in this photo from Canada; the forewing may also have only a single visible line
western North America: Manitoba to British Columbia, south to California and New Mexico
mixed and deciduous woodlands; adults are nocturnal and come to light
adults fly from June to August
unknown, but larvae have been reared to maturity on gooseberry (Ribes sp.)
