|scientific name Eufidonia convergaria |
common name Pine Powder Moth
Occurs in lodgepole and jack pine forest.
Adults fly in spring, peaking in early to mid June.
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.
Not of concern.
Larvae feed on various species of pine, including Lodgepole Pine (Pinus contortus) and Jack Pine (Pinus banksiana) (Prentice 1963, as E. notataria).
Northeastern BC east to Newfoundland (McGuffin 1977).
