Flea beetles
and grasshoppers are two insects that damage blueberry bushes by chewing on the leaves. Click on the links below to learn how to recognize damage caused by these insects, as well as information about how to manage them,

Flea beetles are oval-shaped and shiny copper-bronze or metallic blue in color. They can cause serious damage during the summer by chewing small holes in the leaves. Large numbers may completely defoliate large areas in both crop and pruned fields.

Grasshoppers are generally elongated insects with narrow, leathery forewings; large, membranous flying wings; and chewing mouthparts. They vary in color from greenish-yellow to gray to brown to browish-black. They feed by chewing the foliage and by biting and chewing on berries.
