Insects that can cause defoliation of blueberry plants include blueberry flea beetles and yellownecked caterpillars. Click on the links below to find information on how to detect and manage these insect pests.

Blueberry flea beetle adults are less than 0.25 inch in length, oval shaped and shiny copper-bronze or metallic blue in color. These beetles can cause serious damage during the summer months.

Yellownecked caterpillar adults are light brown moths with a wingspan of 1.5 inches to 2 inches. Young larvae can skeletonize blueberry foliage. Older larvae are able to consume entire leaves and may completely defoliate small plants.
