She'll bite the head off of her mate and eat it--but the mating process continues unabated.

The praying mantis and its relative, the Chinese mantis, are in their courtship season. The current study focuses on the praying mantid, Pseudomantis albofimbriata, a moderately size dimorphic species with relatively large males. The difficulty understanding why this species has evolved to behave in such a way is largely due to sexual cannibalism taking on many different forms in respect to the role and behavior of each sex, the potential benefit to each sex and the timing of when the courtship/copulation takes place (Suttle 1999). Cannibalistic females of such species may be more likely to gain nutritional benefits from male consumption, which translate into increased fecundity. Dismounting may occur sooner in the wild because there is more cover for them, as well as more movement to distract the female (e.g. Males choose to keep their heads: Preference for lower risk females in a praying mantid. The research suggests that when a male mantis is eaten by the female after mating, more of the male’s body material is passed … Sexual cannibalism is also found in other invertebrates, including a relative of the praying mantis, the Chinese mantis, and scorpions. One extreme case of a reproductive (or mating) cost is sexual cannibalism. 10 Fascinating Facts About Cockroaches. Insects: The Most Diverse Animal Group in the Planet. William D. Brown, Katherine L.

An extreme example of sexual conflict is sexual cannibalism, a remarkable phenomenon that has most commonly been observed in insects (praying mantis), arachnids (black widows), and amphipods (Gammarus pulex). The reproductive process in a majority of mantis species is marked by sexual cannibalism whereby the female eats the male after mating has taken place and is an ongoing subject of research. How aggresive the cannibalism is, differs between species. The most common and widely researched form of cannibalism seen in insects is sexual cannibalism. You know, like a praying mantis eating another praying mantis, or a human eating another human. This behavior, which occurs in less than 30 percent of all mating sessions in the wild, may have evolutionary advantages for the praying mantis species. Yes, it happens.

According to a study published Wednesday, the mantis' proclivity for devouring her mate may have evolved to better provide for her offspring. Temperature must range from 21 to 40o C and the humidity about 60% for African praying mantis and should vary a little depending on any other species you propose to rear. For over a century the praying mantis has been considered by biologists as a prime example of sexual cannibalism. The cannibalistic females improved their health and produced heavier egg sacs than the noncannibalistic females. 168, 263-269. Fascinating Animal Facts.
