Mantis. This name is commonly applied to the various genera which constitute the family Mantidae of the insect order Orthoptera. They are chiefly to be distinguished by the long prothorax and the enlarged front legs, which are fitted for grasping. They are entirely carnivorous in habit, but do not actively pursue their prey; the insect waits patiently until a fly comes within reach, and then rapidly seizes it with its fore-limbs (see the illustration).
The attitude adopted while waiting for insects to come within reach has given to one species, plentiful in the south of Europe, the name of 'praying mantis' (M. religiosa). This creature, invested with supernatural attributes, figures prominently in Bushman mythology and folklore. One of the most remarkable forms of mantis is the Indian Hymenopus bicornis; it has a flower-like shape and a pink colour. The apparent petals are the much-flattened joints of some of the limbs as it rests quietly among foliage. It is supposed that the resemblance to an orchid-like flower may delude smaller insects into approaching near enough for the mantis to take advantage of its 'alluring' colours and shape.
