Adult females mate and lay eggs soon after they emerge in late May. Adult emergence continues through mid-summer so eggs are deposited over an extended period.
Females deposit eggs individually on bark surface or in bark crevices on trunks or branches. The egg-laying period in Indiana probably continues through late July.
Eggs are a light yellow color, oval shaped, and about 4/100 of an inch long.
Each female lays about 75 eggs during her lifetime.
