 Cucumber beetles damage garden and agricultural plants in two ways. Larvae, sometimes called rootworms, feed on the roots while adult beetles feed on leaves. Large populations can cause significant damage in both gardens and agricultural fields.
Spotted cucumber beetles (right) look superficially like lady beetles except for color. They are yellow/green instead of orange/red. There also is a striped cucumber beetle with similar life history and control.
For gardeners one of the best controls against all leaf feeding beetles is to use row covers when beetles are present. Row covers protect young plants from feeding damage. Neem-based insecticides can also be safely used to prevent feeding.
