In general: Praying mantises have segments on their abdomen(=belly). The amount of segments differs for males and females. This is a reliable method to use for sexing nymphs, the bigger they are the easier it is to see the difference.

Specifically for C. gemmatus: Using the segment counting remains the most reliable way for this species. Females often have a wider abdomen, visible from L4/L5 upwards. Adult females will be wider, a bit longer and have a thicker abdomen.


Adult stage:

Females will be adult in L8, Males in L7

Amount of molts can sometimes differ 1 when they are kept under extreme conditions. Both adult sexes will have wings, but especially the males are capable of flying short distances.

Sexual maturity:

Females will be sexually mature after 2-3 weeks, males after 1-2 weeks. The mating can last several hours.

Oothecas & incubation

Oothecas are usually around 4cm. They are elongated and pretty flat. They have a brown colour. Females can start laying oothecas when they are 4-5 weeks old, with an interval of 7-14 days. They can lay up to 8 oothecas.

Incubation time for the oothecas is around 4-8 weeks, depending on temperature. Usually around 40 nymphs hatch.
