Potential problems with identification

Diabrotica undecimpunctata duodecimnotata Harold can be separated from other subspecies by the following features: abdomen is black medially in D. undecimpunctata duodecimnotata, entirely yellow in D. undecimpunctata tenella and entirely black in D. undecimpunctata undecimpunctata; legs, usually only femora, partly pale in D. undecimpunctata duodecimnotata, but entirely black in D. undecimpunctata undecimpunctata; spots on elytra in D. undecimpunctata duodecimnotata are smaller than in D. undecimpunctata undecimpunctata and D. undecimpunctata howardi. Diabrotica undecimpunctata duodecimnotata is smaller and more slender than Diabrotica undecimpunctata howardi.
