| description |
A yellowish to orange species with two prominent small black spots on the middle of the wings along the commissure. There are two yellow or orange parallel submedial lines on the top of the head, with a broad white midline in between. The pronotum has a Y to M-shaped mark, sometimes with the anterior margin colored as well. Much of the scutellum is black except for the lateral triangles; this bold black scutellum is diagnostic for this species, though in some specimens the scutellum is pale. The black mesonotum sometimes is visible through the pronotum. The costal margin of the wings has a small black mark in the middle, and the wing tips are smudged with brown; there is a bold pair of black spots along the inner margin of the wings near the tips. In var. rufomaculata, the clavi of the wings is a bold, bright red. In all forms, the face and thoracic venter are pale. Adults are 2.6-2.9 mm long. (Dmitriev & Dietrich, 2007)

| comments |
This species is most similar to E. vagabunda, as both species have black spots in the middle of the wings. However, the spots tend to be much larger in E. octonotata, and there is a prominent pair of spots along the inner margin of the wings near the tips. Additionally, the middle of the scutellum is black in octonotata; vagabunda lacks this black. |
