Stripe shield bugs are solitary animals. During the mating season, they emit acoustic signals via abdominal vibrations, which are passed on to potential mates via plants. This is how the couples find each other.
Mating takes place in early summer. The females lay their eggs and attach them to leaves and stems of their food plants. Hatching of the larvae takes just over a week. After hatching, the mother guards the larvae. Her threatening-looking striped dress helps her to ward off predators.
The new generation of bugs is already developed between July and August. For hibernation, the loners seek out dry ground litter or plant cushions.
