Indiana, USA – September 2019
In the last century, various species of mantis were introduced to North America from all over the world because they were hoped to be useful in pest control. For some time their eggs, which were deposited in so-called ootheques, were sold to establish praying mantises in gardens.
However, they were not successful because their populations could not adapt quickly enough to the pest plagues that occurred. Their distinct cannibalism also stands in the way of their population development. In addition, they eat everything they can overwhelm and make no difference whether their prey is pests or beneficials. Mice, reptiles and even small birds can also fall prey to them.
The green variant is a pregnant female.
