Mystery Picture #23
The spotted cucumber beetle is a 1/4 inch long yellow-green insect with 12 black spots on its back. It overwinters as an adult in protected areas near buildings, in fence rows, or in wood lots. The adult feeds on foliage, pollen and flowers of cucumbers, muskmelons and watermelons. The larvae of this insect live in the soil and feed on plant stems and roots. This insect can be a serious economic concern because it carries bacteria in its gut that causes bacterial wilt of cucurbits (cucumbers, for example). The wilt disease causes plants to die almost overnight.
