Other Common Names
Paddle Caterpillar (larva)
Explanation of Names
FUNERALIS/FUNERARY: probably refers to the traditional black color related to funerals, as much of the larva and part of the adult is black
Identification
Adult: forewing longitudinally bicolored (light gray on costal two-thirds, black along inner third, with sharp dividing line); broad basal dash has large tooth pointing toward costa; in melanic indidivuals, the light gray is replaced by very dark gray
hindwing white on basal half, shading to gray on distal half, with dark gray veins
Larva: early instars brown with white markings; fourth instar black with middorsal light yellow markings that are triangular to elliptical with transverse black streaks in the center, and a pair of long black hairs with flattened tips that resemble paddles - hence the common name of Paddle Caterpillar
Range
patchy distribution: Manitoba to Nova Scotia, south to Maryland, plus Georgia, Mississippi, Texas, and along the west coast from California to BC (apparently missing from much of the midwest and several southern states)
Season
adults fly from May to August
larvae in July and August
Food
larvae feed on leaves of alder, apple, birch, blueberry/huckleberry (Vaccinium spp.), cottonwood, dogwood, elm, hazel, hickory, maple, oak, willow
Life Cycle
two or more generations per year in the south; one or two in the north
