Potential problems with identification

Diabrotica militaris Jacoby is very similar to D. m1n, D. m2n and D. fasciata Kirsch. They can be separated by the following features: band color is metallic black green in D. militaris, but metallic black blue in D. m1n and D. m2n; round yellow spot on the basal band is larger in D. militaris than in D. m1n; tibiae in D. militaris are paler than in all other species; the size and the shape of the band edges is different in all four species. The shape of the internal sac sclerites allows distinguishing Diabrotica militaris from all other species.
