Squash beetle, which is native to Central and Eastern North America, belongs to the family of lady beetles (Coccinellidae). Most insects in this family are beneficial, often eating large numbers of pest insects such as aphids. The exceptions are the squash beetle and the Mexican bean beetle. The squash beetle is an occasional pest on cucurbits, and the Mexican bean beetle is a common pest on beans, especially in the lower Midwest.
