Forewing white heavily stippled with brown, broad brown AM, PM and terminal bands; hindwing ochre-brown with dark brown mottling and PM band. Discal spots relatively large and conspicuous. Female slightly smaller and paler overall. Very similar to E. discospilata, but males are larger and darker. Genitalic dissection is required to confirm identification (see McGuffin 1977). Treated as a subspecies of E. notataria in some older works.

Adults are diurnal but are also attracted to lights at night. The larva is green and slender with a pale lateral line, mimicking pine needles. The pupa overwinters (Wagner et al. 2001). McGuffin (1977) gives a detailed description of the immature stages.
