Potential problems with identification

Diabrotica caveyi is very similar to D. fasciata Kirsch. They can be separated by the following features: scutellumscutellum:
small, usually triangular shield between the bases of elytra
is brown or black in D. caveyi, but yellow in D. fasciata; pronotumpronotum:
the notum of the prothorax with highly sclerotized pronotal disc
is wider, slightly transverse in D. caveyi, but very narrow, quadrate in D. fasciata; yellow stripe between bandsbands:
(here) transverse maculae on the beetle elytra
is wide in D. caveyi, but very narrow in D. fasciata; antennae in D. caveyi are thicker and slightly shorter than in D. fasciata.
