Armored cricket or Koringkriek is actually a katydid ((family Tettigoniidae, subfamily Hetrodinae). All species of Hetrodinae have tiny wings, completely hidden under their large, spiny pronotum. Few animals eat these insects, which defend themselves by squirting bitter tasting blood from pores on their legs and thorax at attackers. Armored crickets feed mostly on plants but occassionally turn into cannibals. Acanthoproctus cervinus is common in dry habitats of the Cape; the front edge of its pronotum sports large "horns" and an additional "horn" is present on the head.
