King Cricket (Libanasidus vittatus) Family Anostostomatidae

Otherwise called the Parktown Prawn, are extremely large, nearly 3 inches.
They are nocturnal, emerging from their burrows in the early evening.

They have a varied diet which includes snails, insect grubs, earthworms, seedlings, fallen fruit and dog dropings. Adults can consume up to 4 snails per night.

When disturbed they can sqeal like a pig and eject a foul-smelling faeces.

They like well-watered, rich soils in city gardens.

I think this one was dying as it was flopping around and not getting very far.
