Diabrotica tortuosa Jacoby is similar to D. viridula (Fabricius) and D. scutellata Jacoby. They can be separated by the following features: elytra surface in D. tortuosa is almost not sulcatesulcate:
bearing the carinae or ridges on the elytron
, but with well-defined sulci in D. viridula and D. scutellata; there are three bandsbands:
(here) transverse maculae on the beetle elytra
and one macula on elytra in D. tortuosa, but only two macula present on elytra in D. viridula and D. scutellata; the head is orange or rufous in D. tortuosa, but green in D. viridula.
