To the Mantodea belong about 2400 terricolous species of dimensions varying from 2,5 to 16 cm. The body is elongated, with frequent homochromy, in many exotic species the coloured liveries reinforce the effect of the terrifying attitude they take to drive away the competitors.
The head is small, mobile with developed compound eyes and three ocelli; the antennae are more or less long and filiform.
The mouthpart is masticatory with short, strong and slightly asymmetric mandibles.
