Mantids are carnivorous insects that feed mainly on other insect. Mantis religiosa, also named praying mantis or European mantis, is the most common species in Europe.
Praying mantises are solitary insects which can grow to a length of around 8 cm (the males are smaller and more slender). They are usually either green or light brown in color allowing them to hide undetected amongst shrubs or grasses. Their front set of legs is lined with spines that help them hold their prey. A curved horn-like spike also helps them catch their prey and they sometimes use this to punch at predators.
The photo of the praying mantis was captured only a few kilometers outside of Basel in the northwestern corner of Switzerland. They are very rare here and difficult to find.
