Larvae within hibernacula become active when bud growth begins in spring. They feed on buds for a short time, then tunnel into emerging shoots, where they pupate. Wilting of newly formed shoots is the characteristic sign of damage. The adults that emerge from pupal cases are small, grey moths with a distinctive ridge of dark scales across the forewings. These moths emerge in early June, during pecan nut set.
Females lay small greenish-white eggs on the blossom end of the nut, usually near the calyx.
One or two eggs are laid per nut cluster. This text was extracted from the publication, SRL-82.
