Savanna-Brown Stink Bug

Brown Stink Bug

Order: Hemiptera

Family: Pentatomidae

Genus: Euschistus

Species: E. servus

General Characteristics: Green Stink Bugs and Brown Stink Bugs. Adult stink bugs are shaped like a shield, but the nymphs (juveniles) can look very different from their adult stage, having very short, stubby wing pads, and are often a different color than the adults. In particular, green stink bug nymphs have a flashy display of black, green, orange and yellow. The brown stink bug adult should not be confused with the beneficial Spined Soldier Bug which feeds on caterpillars and other insect pests. To tell these two apart, look at their feeding beak or needle-like mouthpart. The beak of the brown stink bug is slender to pierce through delicate plant tissue. The beak of the spined soldier bug is thicker so that it can harpoon into their insect prey.

Special Adaptations: Stink bugs feed on over 52 plants, including native and ornamental trees, shrubs, vines, weeds, and many cultivated crops. Stink bugs build up on these hosts and move to soybeans late in the season as their preferred foods mature.
