Breeding and reproduction of the Chinese Mantis

You can breed Chinese mantises in captivity. Some companies breed this mantis species to sell them as natural predators in greenhouses. The companies sell the egg sacs (ootheca) to greenhouse farmers. When the young mantises hatch in the greenhouse they will eat all pest insects like aphids and small flies.

If you want to breed Tenodera sinensis yourself, you need a male and a female that are full grown for at least 2 weeks. How to see if you have both sexes, you can use this sexing method. Then you need to place the male and female together in one enclosure. Make sure the female has eaten A LOT before you do this. Even then it is possible that the female will eat the male before, during or after mating. If mating has occured you should separate both mantises again. After one mating the female mantis will produce fertilized eggs for the rest of her life. She will produce foam-like egg sacs called ootheca. In one egg sac of a Chinese mantis you can find between 30 and 100 eggs. She will produce 3 to 7 egg sacs in her life if she has enough food.
Keep the egg sac in the same conditions as you keep the adult mantis. The eggs will hatch in around 6 weeks. If you plan to release the baby mantises into nature, make sure the eggs do not hatch in winter. If you want to postphone hatching of the eggs you should keep the ootheca at 8 °C (or between 6 to 10 °C), like in your attic, basement or garden house. If you find an ootheca in nature you can leave it there, the mother knows what she is doing and probably the eggs will be safe in winter. Want to read more about caring for mantis eggs?
