A praying mantis can bite, but its bite is not powerful enough to harm a human. The praying mantis bite is not poisonous or lethal.
Praying mantises are insects that are sometimes kept as pets, and some individuals raise and breed them. They are not aggressive and only bite when mistaking a finger for prey.
A praying mantis must be kept in a climate-controlled area and be fed regularly. If this process is kept up throughout the life of the mantis, it can live to be slightly over 1 year old. The mantis molts several times over its lifetime and eventually gains wings, which allow it to fly around in its enclosure.
