| description |
A yellowish to white species with a bold, vibrant orange or red color pattern. The vertex has parallel submedial lines, often with lateral branches, and a dark red midline. The face is brown or black, and the thoracic venter is entirely dark. The pronotum is largely dark with pale lateral margins or pale with two longitudinal stripes. The scutellum is largely reddish-orange. The wings have broken orange-red oblique vittae, and there is a dark spot along the costal margin of each wing. Adults are 2.6-3.0 mm long. (Dmitriev & Dietrich, 2007)

| comments |
There are three species of Erythroneura that feed on dogwood and are very similar in appearance; this includes E. rubrella which is a vibrant red color, E. corni which has extensive red markings on the head (compared to E. rubrella, which has limited, less bold markings and has a brighter red color pattern), and E. ontari which has a less vibrant and bold color pattern. A fourth species that feeds on grape, E. rubra, is also very similar in appearance to E. rubrella and E. corni, though it has a pale midline on the top of the head. Due to the similarity between these four species, in some situations a species level identification may not be possible, or be a best guess at most.
Furthermore, identification is confounded by that the fact that E. ontari may be a variant of E. corni rather than a separate species. Dmitriev & Dietrich,
2007 note that "they are often collected together and differ primarily in the length of the dorsal branch of the pygofer process. However, intermediate forms were not found." |
