Female praying mantises are well-known for attacking and cannibalising their mates throughout or after a sexual encounter, however proof is rising that some males assault too, and that successful a combat is essential for profitable mating.
Sexual cannibalism is frequent amongst praying mantises. Typically, the feminine is the aggressor, which inspires males to strategy the feminine rigorously and cautiously when mating.
But nathan burke and gregory holwell on the college of auckland, new zealand, say some male praying mantises go on the assault as a substitute.
They wrestle and typically severely injure the females in an try to mate and keep away from being eaten.
