Catching, housing, selling or breeding of Mantis religosa religiosa (European mantis), the only naturally living mantis in Germany, is strongly forbidden wihtin Germany. It is protected by German nature conservation law.
However, many more subspecies of Mantis religiosa occur in other countries.
Care (enclosure size and set-up, lifespan, food etc.) can be compared with Hierodula patellifera. But be aware of an eventual diapause (overwintering stage, mostly oothecae). Therefore, check the habitat of the species origin.
