| description |
Males are yellowish, with the legs sometimes tinged with orange and the claws infuscated. The scutellum and pronotum are typically black, though in some individuals the center of the pronotum can be yellow. The head has two black spots in the middle. The wings are partially yellow, contrasting with a black band on the clavi (inner part of the wings) that narrow before following the commissure to the wing tips, where a triangular-shaped mark extends from the apex of each wing; the commissure (inner edge of the wings) is yellow. Females are white, tan or stained with orange. The claws and frontal arcs on the head are lightly infuscated. The wing pattern varies from almost as dark and extensive as the male but with a dark blotch at the apex of the crown and the center of the pronotum paler than the lateral margins (which are dark), to having almost entirely white or tan wings. There are light brown coronal spots, brown speckling on the pronotum, and dark patches along the clavi and at the wing tips. Adult males are 4.3-4.8 mm, females are 5.1-5.9 mm. (Hamilton, 1983) |

This species is one of several Evacanthus found in North Carolina that have a similar color pattern: bellaustralis, chlamidatus, and ustanucha. See each species' respective page for how to identify each species. All three species have identical genitalia; however, they are not variants of a single species since long series collected in different localities reveal little variation in the characters. The almost entirely pale corium (the thicker basal half of the wing) is unique in this genus.
There are 134 specimens collected from GSMNP and Highlands in the Canadian National Collection. |
