The eggs of the mantis are laid in late fall and hatch in early spring. In nature, egg cases can be found in open fields, stuck to the top or middle of tail grasses and stems. The eggs are laid in a foamy material secreted from the abdomen of the female. This material quickly hardens to protect the eggs, resulting in the production of a light brown, walnut sized, irregularly shaped mass with a rough surface. At the time of birth, newborn mantis hatchlings are about 3/8 inch(1cm) in length. Typically whilst hatching, between 50 and 100 nymphs squeeze headfirst through the cracks in the egg case. The hatchlings dangle upside-down below the egg case until the hardening of their exoskeleton takes place. Hatchlings first appear as small, white creatures with two tink black eyes. Within minutes, the numpohs are moving about on thier own. Nymphis do not feed for the first day or two following hatching, but will soon begin to capture and eat other small insects. Mantis development takes place thjrough a process known as incomplete metamorphosis. There is no larval or pupal stage. TThe numphs are similar to the adults eccept that they are smaller, they lack winfs, and they are not sexually mature. the three stages of a mantis's development are egg, nymph, and adult. During their lives the nymphs grown and shed their exockeleton 6-9 times. Upon reaching adulthood, the animals mate, females lay eggs, and both parents die, all within a short period of time.
The exoskeleton of the mantis provides support for the body. However, it does not grow, so it must be shed as the animal grows. In this process, a new soft exoskeleton develops under the sureface of the old one. The old one splits open, exposing the new exoskeleton. The new one expands quickly and hardens. The first molding take place around 12 days after hatching if the nymph has optimum growing conditions and a continuous supply of food. (partly becuase insects are polkilothermic, or coldblooded, time bewteen molts may vary.)
Once arrived, fasten the mantis egg case to a stick. This can be done in several ways. You may run a thread through the outer layer of the case and tie it to the stick, use white glue to attach the case, or bend a paper clip to hold it in place. Add the eggs and stuck to your habitat. Place the habitat in a warm area and abserve it each day. Hatchlings should take place in approximately two weeks, depending on the conditions in the room and time of year. Shortly after the eggs hatch, it is important to sperate the nymphs into jars so they don't eat each other and add live insects as feed. You can do this either by catching them in your garden or purchase and use the flightless fruit fly kit to feed the yound mantises which can quickly become cannibalistic when hungery. Use the bristles of the brush to gently push one of the mantis hatchlings into an empty jar for closer observation or transportation. If hundreds of nymphs hatch and you don't have enough fruit flies to feed them you should release some mantis hatchlings into your garden so they have a possibility of survival. Not that breeding and releasing of insects is not usually a good idea becuase of the natual balance in the ecosystem. However in this case as praying mantises are beneficial insects which have been used to keep gardens clean of flies and other small insects for hundreds of years, there is no problem for the environment.
First thing you should know is breeding is not for the new hobbiest, many factors need to be set and sometimes things can go wrong which will end in early death of your pet. Ok lets get started on what needs to happen if you want to try it. A mantis is ready 2-4 weeks after maturing, which is after its last molt and the indication of wings. When you deside to mate a male and female mantis, make sure they have alot of room(idealy an open room like a bathroom or bedroom) you want to make sure the male has enough room to either run away or even better, fly away. Before you introduce them for mating, over feed the female, this is the when the female has a big chance to cannabilize on her mate. When the mates are introduced the male may take up to a full 24 hours before mounting the female, and another 24-48 hours to connect, after connecting it could take another 24 hours for him to finish(Please not that these are worste case senarios, mating could take as little as a few hours after introduction!). Once the deed is done, IMMEDIATELY remove the male as soon as you notice he is off her back, if not removed in time he will get eatin, even after mating is done. It is important now to continue to over feed her, do not force feed/nor hand feed her, just to leave more food in her container, if she is pregnant and fertile she will eat alot of food, even when it looks like she cant. If she is well fed, you can expect an oothecae within days after mating. Depending on the species you may get alot of oothecae throughout her life with only one mating. Just know that if her cage is not suitable for her she will not lay an egg case for you, again, depending on the species you may need to put in different sized branches and sticks, leaves and foilage. If she fills comfortable... she will give you a gift of many, many babys to come.
