Thespidae is an interesting family of tropical mantises. Its members can be challenging to find, since they tend to be small, drab, and well-camoflaged in their habitats.
Females are wingless. They tend to be larger than males, and invariably have a metallic blue color on the inside surfaces of the forelegs.
Though members of a relatively small family, Thespid mantises are highly diverse, each species seeming perfectly evolved to fill a certain microhabitat.
