Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONATechnical Description, Adults: Forbes (1948)Technical Description, Immature Stages: Wagner et al. (2001)                                                                                 
Adult Markings: This beautiful species is on the wing in the early spring together with the two other members of the genus. Its green color and bold lines makes it unmistakeable but the color fades quickly in pinned specimens.
Adult Structural Features: Unlike the other two members of the genus, this species lacks the hair pencil on the hind tibia of the male. Its valve differs by having the sclerotized anal edge of the valva rounded (pointed in the other two species). The aedeagus has a cluster of cornuti which are absent in the other species. In the female the ductus and corpus bursae are more tube-like than bag-like, there are two rows of spines in the ductus bursae and two distinct signa in the corpus bursae, quite unlike the other two species.
