Damage, symptoms and biology

Sabulodes edwardsata is a relatively uncommon innocuous solitary defoliator.

Mature larva to 32 mm long. Head is reddish brown with a white herringbone pattern over the vertex of each lobe. Body, robust, green with a faint dark green middorsal pin stripe; prominent subdorsal white stripes extending onto the head; white spiracular stripes.

This species overwinters as a mid-instar larva. Larvae are present from April to June, pupation occurs in June, and the adults emerge in July. Eggs are laid in July (presumably on foliage) and hatch soon after. Larvae emerge in August and feed until the weather cools in fall.
