Blueberry Spanworm (Itame argillacearia (Packard))

Judith Collins, H.Y. Forsythe, Jr. and, David Yarborough (November, 1995)

Summary

Infestations of blueberry spanworm may be confined to isolated areas or damage may be widespread. Large numbers of spanworm larvae may completely defoliate areas in both crop and pruned fields. Early in the season, the larvae damage the berry crop by eating flower buds and blossoms. Later larvae chew out notches on developing leaves. Crop fields may be dotted with areas that appear burned. This fact sheet provided information on symptoms, significance of damage, and links to extension educators that can help.
