Also known as an Armoured Ground Cricket, this is a wide-bodied, flightless species that typically grows to a body length of about 5 cm.

The pronotum bears several sharp, conical spines. The mandibles, or main biting jaws, are powerful; they can inflict a painful nip and they permit the insect to feed on material such as tough herbage or carrion.

When their attackers –birds, lizards and spiders – make their move to feast on these crickets, they expel toxic blood (called “haemolymph”) from the gaps in their bodies to avoid being eaten.
