Mantises can be found all over the world, in environments in which the winters are mild and the vegetation harbors adequate prey. While their closest relatives include
cockroaches, mantises (like
crickets) have historically managed to avoid the ick factor with which humans commonly regard insects, and have often been kept as pets. One important quality may be their ability to follow motion by turning their heads, which can make them seem more expressive and intelligent than other insects. Despite the reputation of the Praying Mantis for sexual
cannibalism,
entomologists are uncertain whether such behavior is common in the wild, or whether it is increased by the stresses of captivity. Whatever the case, most mantises encountered
in situ are the larger, more aggressive females, while the males tend to be elusive and retiring.
