The plague soldier beetle or green soldier beetle (Chauliognathus lugubris) is a species of soldier beetle (Cantharidae) native to Australia. It has a flattened body to 15 millimetres long with a prominent yellow-orange stripe behind the black prothorax. The abdomen is yellow-orange but is mostly obscured by the metallic olive green elytra. The beetles often form large mating swarms.
