Miomantis caffra (common name: Springbok Mantis) is a species of praying mantis native to Southern Africa. It appeared in New Zealand in 1978, and was found more recently in Portugal and Los Angeles, California, in North America, likely spread through the exotic pet trade. Females are facultatively parthenogenetic and unmated females can produce viable offspring.

Description
Ootheca
The ootheca (egg case) of M. caffra is 12–30 mm long with rounded sides, soft creamy-brown, fawn or beige with a terminal handle-like extension. Hatching is not synchronised, and nymphs may emerge over a period of weeks or even over two seasons. Refrigeration of ootheca in the exotic pet trade can delay their hatching.
The oothecae are extremely hardy, and can survive winter to hatch even in the far south and alpine regions of New Zealand.
Nymphs
The nymphs are green or brown, body often longitudinally striped, limbs mottled, tip of abdomen curved upwards. Significant colour variation exists in nymphs and sub-adults, with bodies varying from pale straw-colour, bright green, and reddish brown, and legs varying from pale to almost black. Nymphs of M. caffra are cannibalistic, and will attack and eat one-another even in the presence of alternative prey. They do not discriminate against killing their own siblings, and in encounters between two nymphs, the larger usually eats the smaller.
Adults
Adults of M. caffra are usually 32–60 mm long, pale green or brown, occasionally with pink or purplish colouration near base of fore-wing; hind wings are green or bright yellow. Pronotum narrower than head, approximately 1/3 of body length, rounded dorsally and swollen over the leg attachment. There are dark pigment spots on the inner surface of the fore-femur. Males are smaller, more slender and have longer antennae than females. The abdomen of an egg-bearing female extends well beyond the wings.
Behavior
In its natural environment, M. caffra tends to hide under leaves. Males are sometimes eaten by females when mating.
New Zealand
In New Zealand M. caffra is commonly referred to as the springbok mantis or the South African praying mantis. The first specimens to be found in New Zealand were nymphs collected by an Auckland schoolboy at his home in New Lynn, Auckland during February 1978. These were reared to adulthood and a colony based on them was established and maintained by the Entomology Division, DSIR. Initially their identity caused problems as the specimens were unlike any other Australian or Pacific species examined. Finally Dr A. Kaltenbach of the Naturhistorisches Museum, Vienna, identified the specimens as a common Southern African species, Miomantis caffra. Although not considered a pest species, it is thought to be displacing the New Zealand native species (Orthodera novaezealandiae) in urban environments of northern New Zealand.
