Indian Bark Mantis(Humbertiella genus)
Mantises protect themselves by camouflage, most species being cryptically colored to resemble foliage or other backgrounds, both to avoid predators and to better snare their prey. Humbertiella is a genus of praying mantids in the subfamily Gonypetinae found in Asia. They have a cryptic camouflage resembling tree bark. They are dorsoventrally flattened so as to eliminate shadows that might reveal their presence.
The closest relatives of mantises are termites and cockroaches (Blattodea), which are all within the superorder Dictyoptera.
Because of the superficially similar raptorial forelegs, mantidflies may be confused with mantises, though they are unrelated.
Mantises are unique to the Dictyoptera in that they have tympanate hearing, with two tympana in an auditory chamber in their metathorax. Most mantises can only hear ultrasound.
Mantises have stereo vision. They locate their prey by sight; their compound eyes contain up to 10,000 ommatidia. As their hunting relies heavily on vision, mantises are primarily diurnal. Many species, however, fly at night, and then may be attracted to artificial lights.
