The European mantis (Mantis religiosa) is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises). Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose. It resembles a praying attitude. Both males and females have elongated bodies with two pairs of wings. The most striking features that all Mantodea share are a very mobile, triangular head with large compound eyes and their first pair of legs (the 'raptorial legs'), which is highly modified for the efficient capture and restraint of fast-moving or flying prey.

In Germany, M. religiosa is listed as Gefährdet on the German Red List on the basis of an assessment from 1998. It is not supposed to be caught or held as a pet. At a global level, it is assessed by the IUCN as least concern.

The great variation in the coloration of M. religiosa from different shades of yellow, brown, green, and sometimes black has been the cause of numerous hypotheses and studies for over 100 years. However, no generally accepted answer about reason, benefit, or mechanism of the coloration or the change of coloration has been found.

Di Cesnola observed in 1904 that green mantids were found on fresh green grass, whereas brown individuals seemed to prefer brown grass burned by the sun. When forced to change the location as to no longer match their coloration, almost all the ‘not matching’ animals were killed by predators such as birds. This indicates a camouflaging purpose of the coloration.

Przibram also observed in 1907 that a change in temperature can trigger a change in coloration: animals that hatched in a cold environment turned green after moulting when heat and sunlight were provided. Without the change in temperature and only a change in the color of the background, no change in coloration occurred. This finding contradicts with Di Cesnola, who claims to have observed the animals within the same time and location (and therefore the same temperature).

The sexual behavior of praying mantids in general is curious, so has received interest from scientists over the last century. The differences between the various species are well known.

In M. religiosa, courtship and mating are separated into two steps: Preliminary courtship begins with the first visual contact between the animals and ends with the first physical contact. Copulation begins with physical contact and ends when the spermatophore is deposited.

Only a few days after the final moult into adults, the animals begin to show interest in the opposite sex; this point is marked as the achievement of sexual maturity. Males have been observed to be most attracted to females during the middle of the day when the temperature is hottest. Theories are that the female pheromones are most volatile in the heat and that also the male, as a thermophilic insect, is most active.

Instead of just observing them, sexually mature males approach sexually mature females when they see them, but due to the physical superiority of the females, males of M. religiosa face certain challenges in doing so. When a female spots a male, she is very likely to attack and kill him (see also: Sexual cannibalism). Therefore, males can be observed to be very slow and cautious in their approach; after spotting a female, the male usually freezes and turns his head to look directly at her. Since the foveae in his eyes face directly forwards, he has the most accurate and detailed view of her and can watch every one of her moves. He then proceeds to approach her from behind. Males can be observed to stop as soon as the female turns her head or even moves. Mantids are very good at detecting moving structures, but are almost unable to see immobile objects. Using this ‘stop-and-go’ tactic, the male stalks closer to the female. This can often take several hours. Depending on the environment, males sometimes show a light ‘rocking’-behavior which is believed to imitate the leaves of surrounding plants to blend in with the background. Males doing this had no higher probability of being detected and attacked, which supports this hypothesis of concealment.

No mention of male or female courtship has been made in either the field or captivity. The male, in fact, does not win by display; he wins by the absence of display.Once the male is close enough to the female, he opens his wings a little to facilitate his jump on the female's back. As soon as he lands, he proceeds to hold on to her with his raptorial legs. His tibiae fit into a pair of grooves on either side of the female's mesothorax in front of her wing bases.When the male is in a secure position, copulation is initiated. The genitals, which are found on the end of the abdomen in both sexes, look quite different; the males possess a pair of asymmetrical claspers, while the females have an ovipositor. The ovipositor is rather short in comparison to other insects. It is covered in part by the edges of the last sternum. The abdomen of the male curves and twists in a 90° angle around the female's to insert the claspers between the ovipositor and the sternum. The abdomen of the male then contracts in a peristaltic manner. The animals can stay in this position for four to five hours before a spermatophore is deposited inside the female and the claspers are withdrawn. The male then lets go of the female to drop to the ground to get out of her reach for his own safety. After getting away about 50 cm, he stops and freezes for about four minutes before he leaves eventually. This behavior could be interpreted as necessary rest after the efforts of copulating in a safe distance from the female.

The European mantis (Mantis religiosa) is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises).

In Germany, M. religiosa is listed as Gefährdet [endangered] on the German Red List on the basis of an assessment from 1998. It is not supposed to be caught or held as a pet. At a global level, it is assessed by the IUCN as least concern.

Though females of M. religiosa are usually larger and heavier than males (7–9 cm versus 6–7 cm), the antennae and the eyes of male animals outsize those of the females. Along with the forward-directed, compound eyes, simple eyes also are found on the head. These three dorsal ocelli are also more pronounced in males than in females.

Males are often found to be more active and agile, whereas females are physically more powerful. Adult females are generally too large and heavy for their wings to enable a take-off.

Mantids show strong deimatic display from very early life stages on. This behavior can be observed throughout different groups of animals and is used to scare or startle potential predators to give the attacked animals a chance to escape. The deimatic display in M. religiosa involves wing spreading and bending of the raptorial legs to reveal two matched black eyespots with a yellow or white center at the base of the coxae (legs). It makes the animal appear much larger and more of a threat to the attacker. The black eyespots are also a distinct feature for species discrimination of the European mantis. Another unique feature of M. religiosa is its midline metathoracic ear (see Ultrasound avoidance). This “tympanal auditory organ” is an unpaired structure found on the ventral side of the animal on the metathorax between the third pair of legs. Unlike other sound-processing organs found among different groups of insects, the metathoracic ear has a high sensitivity across high and low frequencies and even ultrasound. Therefore, the authors call it a ‘true ear’.

The great variation in the coloration of M. religiosa from different shades of yellow, brown, green, and sometimes black has been the cause of numerous hypotheses and studies for over 100 years. However, no generally accepted answer about reason, benefit, or mechanism of the coloration or the change of coloration has been found.
