Size
wingspan 22-30 mm - MPG and Moths of SE AZ
Identification
Adult: body and wings black with bluish or greenish tint; collar dull orange or red as described by Stretch (1885) except in form "brillians" which has black collar.

Larva: later instars broadly striped across blue and yellow with narrower black bands. CAUTION! black hairs of especially late-instar larvae may cause an allergic reaction
Egg: yellowish or white, laid in clusters of 10-100 on undersides of leaves
Range
sw US: (so. CA to c. TX, n. to Wyo.) / n. Mex. - Map (MPG)
Type Locality: NM
Season
mostly: Apr-Sept - MPG
Food
Larvae are a major defoliating pest of grapes - Vitis spp., and also feed on creeper - Parthenocissus spp. (Vitaceae)
Life Cycle
Overwinters as a pupa enclosed in silken cocoon on the ground amongst leaf-litter. Adults emerge and lay eggs on leaves soon after bud-break in spring. Early instars feed gregariously on undersides of leaves which they skeletonize. Later instars spread out and may defoliate entire vineyards. Several generations per year.
Remarks
Larvae are a severe pest in some California vineyards.
