Both adults and nymphs of the spiny shieldbugs are predatory, feeding on the larvae of other insects, especially on leaf bugs, beetles, aphids and caterpillars. The choice of the prey depend on the season and availability of food. However both adults and nymphs also suck sap from plants. The female lays eggs on tree trunks and leaves. In the spring the larvae hatch, growing to the adult bugs after five moultings. Nymphs become adults by July or August and adults can be found until November. This species usually overwinters as eggs and less frequently as nymphs.
