Aularches miliaris is a colorful grasshopper belonging to the family Pyrgomorphidae found in South and Southeast Asia. The bright warning colours keep away predators and their defence when disturbed includes the ejection of a toxic foam.[1][2]

The insect has been called by a variety of names including Coffee locust, Ghost Grasshopper, Northern Spotted Grasshopper, or Foam Grasshopper and enjoys some popularity as a pet insect.

Description[edit]

Aularches miliaris

The head and thorax are dark green with a canary-yellow band on the side. The tegmina are green with many yellow spots; the legs are blue, with a yellow serrated pattern on the hind femora. The abdomen is black with bright red bands.[1] Two subspecies have been designated, the nominate and pseudopunctatus.

Habits[edit]

It swarms in October, the mating and egg-laying season, collecting on bushes and grasses. It is heavy and sluggish, able to make only short leaps, very visible on vegetation.[1] Outbreaks leading to their damage to cultivated crops are uncommon.[3]

When A. miliaris (of either sex) is disturbed or grabbed, it emits a sharp rasping noise from its thoracic segments. If its thorax is pinched, it also squirts a clear viscous mucus with unpleasant smell and a bitter taste, faintly alkaline, with many embedded bubbles. This foam comes out as a strong jet from apertures in the thorax, and more gently from other openings in the body (ten in total); it heaps up around the insect and partly covers it.[1]
