Mantis
The mating season in temperate climates typically takes place in autumn, while in tropical areas, mating can occur at any time of the year. To mate following courtship, the male usually leaps onto the female's back, clasping her thorax and wing bases with his forelegs. He then arches his abdomen to deposit and store sperm in a special chamber near the tip of the female's abdomen. The female lays between 10 and 400 eggs, depending on the species. Eggs are typically deposited in a froth mass-produced by glands in the abdomen. This froth hardens, creating a protective capsule, which together with the egg mass is called an ootheca. Depending on the species, the ootheca can be attached to a flat surface, wrapped around a plant, or even deposited in the ground. Despite the versatility and durability of the eggs, they are often preyed on, especially by several species of parasitoid wasps. In a few species, mostly ground and bark mantises in the family Tarachodidae, the mother guards the eggs. The cryptic "Tarachodes maurus" positions herself on bark with her abdomen covering her egg capsule, ambushing passing prey and moving very little until the eggs hatch. An unusual reproductive strategy is adopted by Brunner's stick mantis from the southern United States; no males have ever been found in this species, and the females breed parthenogenetically. 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.
Dwarf gourami
Once the nest has been built the male will begin courting the female, usually in the afternoon or evening. He signals his intentions by swimming around the female with flared fins, attempting to draw her to the nest where he will continue his courting display. If the female accepts the male she will begin swimming in circles with the male beneath the bubble nest. When she is ready to spawn she touches the male on either the back or the tail with her mouth. Upon this signal the male will embrace the female, turning her first on her side and finally on her back. At this point the female will release approximately five dozen clear eggs, which are immediately fertilized by the male. Most of the eggs will float up into the bubble nest. Eggs that stray are collected by the male and placed in the nest. Once all the eggs are secured in the nest, the pair will spawn again. If more than one female is present in the breeding tank, the male may spawn with all of them. The spawning sessions will continue for two to four hours, and produce between 300 and 800 eggs. Dwarf gouramis have a fecundity of about 600 eggs.[1] Upon completion, the male will place a fine layer of bubbles beneath the eggs, assuring that they remain in the bubble nest.The male will protect the eggs and fry. In 12 to 24 hours the fry will hatch, and continue developing within the protection of the bubble nest. After three days they are sufficiently developed to be free swimming and leave the nest. When the fry are two to three days old the male should also be removed or he may consume the young.
