Species goedartella (Bronze Alder Moth - Hodges#2457)
Hodges Number
2457
Size
wingspan 10-13 mm
larva to 11 mm
Identification
Adult: forewing white with three broad metallic bronze bands that may be tinted with green, orange, or yellow: a slightly curved basal band, a band near mid-wing that splits into a Y shape before reaching the costa, and a subterminal band that curves from the inner margin toward the apex; labial palps white; face, head, and thorax whitish or pale yellow; antennae with white and brown rings; abdomen brown or grayish; legs brownish-white, darker near joints; hindwing brown to gray, slender, pointed, with wide fringe around perimeter

Larva: body green or pinkish; head shiny dark brown, cervical shield brown indistinctly marked with black
Range
scattered distribution in North America: reported from California, Colorado, Michigan, New Hampshire, Alberta, British Columbia, Ontario, and Saskatchewan - and probably occurs elsewhere
common throughout Eurasia in appropriate habitat
also occurs in Mexico
Habitat
deciduous or mixed woods containing alder and/or birch
Season
adults may appear as early as April but usually fly from June to September, with peak numbers in July
larvae in March and April
pupae in May and June
Food
larvae feed on catkins and shoots of alder and birch
Life Cycle
one generation per year; overwinters as a larva in a shoot or male catkin; inhabited catkins are distorted and frass is ejected through a hole in the side; in late March or April, larva descends on a silken thread to pupate under bark, where many sometimes congregate, and remains there several weeks before pupating; pupal stage lasts four to six weeks
Remarks
North American specimens are slightly larger than the European ones, and the head and thorax are paler.
Adults fly in afternoon sunshine and also come to light.
