Potential problems with identification

Diabrotica hilli Krysan & Smith is similar to D. viridula (Fabricius). They can be separated by the following features: the head of D. hilli is black, but green in D. viridula; the antennae in D. hilli are piceous, but bi- or tricolored in D. viridula, paler than in D. hilli; the legs of D. viridula are also paler than in D. hilli.
