"may be a consequence of warmer water. When receptive to mating, a female blacktip reef shark swims slowly in a sinusoidal pattern near the bottom with her head pointed down; observations in the wild suggest female sharks release chemical signals that allow males to track them. Once the male finds her, he closes to around and follows her with his snout oriented towards her vent. A courting male may also bite the female behind her gills or on her pectoral fins; these mating wounds heal completely after 4–6 weeks. After a period of synchronous swimming, the male pushes the female"

Around 90% of the predatory species of mantises participate in sexual cannibalism. Adult males typically outnumber females at first, but their numbers may be fairly equivalent later in the adult stage, possibly because females selectively eat the smaller males. In ""Tenodera sinensis"", 83% of males escape cannibalism after an encounter with a female, but since multiple matings occur, the probability of a male's being eaten increases cumulatively. The female may begin feeding by biting off the male's head (as they do"
"cannibalism during mating is not common in most mantid species. Two weeks after mating, the females lay egg cases known as ootheca on twigs and branches. The ootheca is long, with each ootheca containing 10–20 eggs. The eggs lay dormant over winter, and if they survive, nymphs will start emerging from the ootheca in early spring. Females will molt approximately 7 times, with their terminal molts being in mid to late summer. Males will molt only 6 times and will have a terminal molt mid to late summer also. Nymphs and juveniles spend all spring and early summer catching as"

Molting can happen five to 10 times before the adult stage is reached, depending on the species. After the final molt, most species have wings, though some species remain wingless or brachypterous (""short-winged""), particularly in the female sex. The lifespan of a mantis depends on the species; smaller ones may live 4–8 weeks, while larger species may live 4–6 months.

A female can be identified from male by her six abdominal segments, whereas males have eight. She also has a much larger abdomen. After mating, the female may attempt to eat the male to increase fertility, which will entail a struggle. The adult female will lay several egg cases (called oothecae) over her lifespan. From each of these oothecae, up to 150 nymphs hatch after six to eight weeks. This mantis can jump around twice its body length, and although adults are capable of flight, some females occasionally"

Males seem to alternate between the left and right hemipenis on successive matings. The female matures one ovarian follicle at a time, the ovaries alternating in production. The sight of a courting male induces ovarian development, sexual receptiveness and then ovulation. About two to four weeks following mating, the female lays her first"

Mantises are sometimes confused with stick insects (Phasmatodea), other elongated insects such as grasshoppers (Orthoptera), or other unrelated insects with raptorial forelegs such as mantisflies (Mantispidae). Mantises are mostly ambush predators, but a few ground-dwelling species are found actively pursuing their prey. They normally live for about a year. In cooler climates, the adults lay eggs in autumn, then die. The eggs are protected by their hard capsules and hatch in the spring. Females sometimes practice sexual cannibalism, eating their mates after copulation. Mantises were considered to have supernatural powers by early civilizations,"

Early researchers thought that because copulatory movement is controlled by a ganglion in the abdomen, not the head, removal of the male's head was a reproductive strategy by females to enhance fertilization while obtaining sustenance. Later, this behavior appeared to be an artifact of intrusive laboratory observation. Whether the behavior is natural in the field or also the result of distractions caused by the human observer remains controversial.

In the late 1980s, they began showing up in southern Idaho, and appear to be migrating northward, adapting to the colder winters along the way. Also found in Mexico. Like all mantids, the California mantis is carnivorous, consuming virtually any other insect it perceives as small enough to be eaten, including other members of its own species. Males and females come together to reproduce but otherwise the adults are strictly solitary. Nymphs hatch in the spring from hard egg cases laid the previous fall."
"with most mantis species, ""S. viridis"" males are frequently the victims of sexual cannibalism. A female produces an ootheca within a few days of mating and can produce several before she ends her lifecycle. Each ootheca produces up to 300 nymphs when it hatches. This species has also been noted to have reproduced parthenogenically. Because of its size and hardiness, ""S. viridis"" is popular among those who keep insects as pets.

Males cannot use these mandibles to bite because they are too long; on the other hand, females have short, heavily sclerotized mandibles which enable them to deliver powerful bites when threatened. Males of many species will also produce ""nuptial gifts"" in the form of packages of nutrient-rich spermatophores that are eaten by the female partner after mating. This has been shown to be correlated to mandible size; in species where the males have large mandibles the ""nuptial gift"" is small or absent, while it is large in species where males lack the"

Mating times for this species are highly dependent upon weather conditions and prey availability. Typically females are most likely to accept a mate and have a successful clutch two weeks after their last molt.

During this period, males fight over females and territory by grappling with one another upon their hind legs, with the loser eventually being pinned to the ground. These males may vomit or defecate when preparing for the fight. The winner of the fight will then flick his long tongue at the female to gain information about her receptivity. Females are antagonistic and resist with their claws and teeth during the early phases of courtship. Therefore, the male must fully restrain the female during coitus to avoid being"
"4.5. Mating occurs in fall and spring, and involves the males biting on to the female's tail to initiate the mating process. In a typical Plethodontidae mating behaviour, the pair will then walk in a line with the female straddling the male's tail and the male will then deposit a spermatophore on the ground and guide the female to it so she may pick it up with her cloaca. This is how they achieve internal fertilization, and the female will lay a clutch averaging 3-10 eggs in a seepage area or wherever she can find moist ground and stay nearby"

The ability to reproduce by parthenogenesis has been recorded in at least two other species, ""Sphodromantis viridis"" and ""Miomantis"" sp., although these species usually reproduce sexually. In temperate climates, adults do not survive the winter and the eggs undergo a diapause, hatching in the spring. As in closely related insect groups in the superorder Dictyoptera, mantises go through three life stages: egg, nymph, and adult (mantises are among the hemimetabolous insects). For smaller species, the eggs may hatch in 3–4 weeks as opposed to 4–6 weeks for larger species. The nymphs may be colored"

They are white or brown and can reach lengths of up to some 40mm long, with distinct markings on the thorax and with a white blotch on the wings. They're called burying mantids because females dig holes in the ground, in which they lay their eggs and then refill the holes.

Most agamas are polygamous. Males may hold six or more females in their territory for breeding. During courtship, the male bobs his head to impress the female. Occasionally, females initiate courtship by offering their hindquarters to the male and then running until he is able to catch up.

Many mantises also have an auditory thoracic organ that helps them avoid bats by detecting their echolocation calls and responding evasively. Mantises are generalist predators of arthropods. The majority of mantises are ambush predators that only feed upon live prey within their reach. They either camouflage themselves and remain stationary, waiting for prey to approach, or stalk their prey with slow, stealthy movements. Larger mantises sometimes eat smaller individuals of their own species, as well as small vertebrates such as lizards, frogs, small birds and fishes. Most mantises stalk tempting"

For example, since female praying mantids are sexually cannibalistic, the male will typically avail of a concealment form of display behaviour. This is a series of creeping movements executed by the male as it approaches the female with freezing of the body whenever the female looks towards the male. However, according to laboratory studies conducted by Loxton in 1979, one type of praying mantis, ""Ephestiasula arnoena"", shows both male and female counterparts performing overt and ritualized behaviour before mating.

Although this mating behavior is similar to the species ""Urolophus halleri"", differences can be seen in the particular actions of ""Dasyatis sabina"".

As they grow, they molt this exoskeleton to allow further growth until they reach their mature size, after which molting will be unnecessary. During the molting process, H. membranacea often does not eat, and avoids exposure to predators as its new shell will initially be soft and vulnerable. H. membranacea is particularly cannibalistic. Cannibalism in this species is thought to increase female fecundity. These huge insects can also tackle highly predatory hornets such as the Asian Giant"
