Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012) | Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD | Technical Description, Adults: Forbes (1948) | Technical Description, Immature Stages: Wagner et al. (2001) | |
Adult Markings: The green color is unique, as is the reduction in the hindwings. Numerous Nemorines are greenish but none have the almost aquamarine color of this species. Sexes are similar. |
Wingspan: 28 mm (Forbes, 1948) |
Adult Structural Features: Both males and females have distinct genitalia with a number of unusual characters which should verify the species in cases where there is doubt. Males have pectinate antennae with extremely long branches. |

Adult ID Requirements: Identifiable from good quality photos of unworn specimens. |
Immatures and Development: Larvae are yellowish, with thorn-like projections on the first thoracic segment (Wagner et al., 2001). The caterpillar seems to be mimicking either grape tendrils or petioles. Forbes (1948) mentions that the caterpillar forms a shelter by folding together leaves, but Wagner et al. were unable to confirm this behavior. More information is needed on the details of its life history. |
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants. |
