This pest is a member of the stink bug family, although typically is about half the size, or smaller, than a stink bug.  It’s originally from southern Africa.  It has a wide host range, but seems to prefer feeding on crucifers.  It’s a sucking insect and its damage is a series of chlorotic spots on leaves (see the pictures of the bug).

Most stinkbugs’ egg masses are barrel shaped and laid in groups of a dozen or more.  The Bagrada bugs’ eggs may be laid singly, or in smaller, dispersed bunches, and are rounder and less barrel-shaped than is typical of stink bug eggs.  They will generally lay eggs on leaves, but unlike most stinkbugs, will also lay eggs in the soil.
