Mature larva to 25 mm long. Head and body green with white flecking; subdorsal and spiracular stripes cream to yellowish white.
This species overwinters in the egg stage. Larvae emerge in June and feed gregariously on older foliage, mature larvae feed individually on the new flush. Larvae pupate in July on bark, branches or on low vegetation. Adults emerge 10 to 15 days later and are in flight from July to August. Eggs are laid in rows on needles.
