The Plague Soldier Beetle (Chauliognathus lugubris) is back in great numbers on a variety of mainly garden plants. They feed on pollen and nectar. Their orange bodies serve as a warning to predators to leave them alone as they taste horrible (not that I have tried one).
In most beetles the front pair of wings (elytra) are a hard covering that protects the hind pair of wings and the abdomen. The Plague Soldier Beetles are different in that they have soft forewings. The identifying characteristics are dark green fore wings, yellow-orange stripe behind head and orange body up to 2cm long. The larvae live in the soil.
