Sexing:

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.

Breeding

Adult stage:

Females will be adult in L9, males in L8

Amount of molts can sometimes differ 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 are sexually mature 4 weeks after their final molt, whilst males are after 3 weeks.

Oothecas & incubation

The oothecas are around 3-4cm big and have an oval shape. The color is usually brownish. Up to 5 oothecas can be laid, with an interval of around 20 days. The first ootheca will be laid around 5-6 weeks after the last molt.

It takes around 5-8 weeks for the ootheca to hatch. Up to 100 nymphs can hatch per ootheca. The freshly born nymphs are around 5mm in size.
