Aularches miliaris, showing some foam

When it is disturbed or grabbed, it makes a sharp rasping noise with its thoracic segments. Then, if its thorax is pinched, it gives off a toxic foam.[2][3] It squirts a clear viscous mucus with unpleasant smell and a bitter taste, faintly alkaline, with many bubbles. This foam comes out as a strong jet from openings in the thorax, and more gently from other openings in the body (ten in total). The foam heaps up around the insect and partly covers it.[2]

Colouring and behaviourEdit

The head and thorax are dark green with a canary-yellow band on the side. The leathery front wings are green with many yellow spots; the legs are blue, with a yellow serrated pattern on the hind legs. The abdomen is black with bright red bands.[2]

Like most noxious animals, it is very visible and slow-moving on vegetation.[2] It pays to advertise, and it does not need to hide.
