The grape flea beetle is an insect that during the winter time hides itself under soil or the wood crevices that are weaved in or around grapevines. They emerge in the early spring to feed on grape buds, mate and lay eggs. Their larvae appear in about two weeks and they then begin feeding on leaves. Adult beetles will emerge in late July and feed on the grapevine leaves. The grape flea beetle causes the most damage when they feed on the buds. This prevents the buds from developing into shoots, which will result in the unfortunate result of a decreased grape yield.
