Green Stink Bug Nymph Coordinating Items Keychain

The green stink bug, Acrosternum hilare, and its cousins are plant pests. The wingless youngsters (called nymphs) get more colourful with each shedding of their skin. Toward the last instar, the nymphs look like this photo, then they shed and become green with orange edges. Stink bugs are shield-shaped and look like they're wearing armour. They can give off an unpleasant odour when disturbed thus earning their name.
