Potential problems with identification

Diabrotica balteata LeConte is similar to D. speciosa (Germar) and D. tortuosa Jacoby. They can be separated by the following feature: there are four bands on the elytra in D. balteata, and only three bands in D. speciosa; tarsi and tibiae are black in D. balteata, but ochraceous-orange in D. tortuosa .
