Eurydema ventralis is a shield bug of the family Pentatomidae, subfamily Pentatominae.

It typically has a two-tone coloration, yellow or red with black markings.

The body is flattened, the head is rounded and the cheeks are sinuous with narrow edges.

This species can damage the cultivations of crucifers (family Brassicaceae) and sometimes also of potatoes and cereals.

In summer, females lay the eggs of the second generation, this time both on crucifers and on other plants (rose, alfalfa).
