Talking about the habits of mantis with insects.

Wearing a wide green film, a pair of front paws tilted to the sky in a praying posture. However, this silent way of praying masks its cruel custom; These begging arms are actually the terrible thing about hijacking. They don't pluck the rosary, but they want to kill the passing larvae.

The serene overall appearance is in sharp contrast with the forelimb weapon known as "hijacking". If it is a grey locust or a white-faced owl, the mantis will pull up the posture of intimidation and deterrence, and the double hook will hook at once accordingly. Then, close the wolf's tip and catch the unconscious victim, so that it has no power to resist.

Grasshoppers and wingless ones are easier to subdue. It doesn't take much time to attack these prey with low risk factor. Generally speaking, just throw a double hook. It is more than enough to deal with spiders in the same way. Just bring a clip in the middle, don't worry about any poison hooks.
