[5] When the wings are folded, the latter spot aligns with a dark mark on the moth's body that covers each tegula.

[6] The dorsal surfaces of the hindwings, when extended, reveal black patches[4] on a white background that becomes greenish-olive near the termens.

[5] Small dark eyespots on the hindwings and the forewings, there found in the discal position bearing two tiny "pupils," are visible even when the wings are folded.

[7] In addition, the faint subterminal line on the forewing (located just basal to the apical spot) is typically scalloped in E. intermedia but is straight or slightly sinusoidal in E.

[8] The species is widespread in the east, the southeast and the center of North America, from Nova Scotia and Ontario to Florida and eastern Texas.

[4] Females lay translucent eggs singly[10] on leaves of the host plant, mainly Vitis spp.

[6] Larvae consume copious amounts of foliage, and when they are ready, after achieving the fifth larval instar,[7] they climb down their host plant and burrow underground, where they pupate.

[10] The newly emerged adults then climb on a plant or some other surface and pump fluid (haemolymph) into their wings to extend them.
