Mantis female lays eggs (ootheca)

I managed to photograph how the praying mantis gives birth to offspring. The intervals of oviposition after copulating depend on the food intake and the overall physical fitness of the female. On average, 11 days are needed for the female to form and deposit an ootheca, which contains around 100 to 200 eggs. Copulation usually takes place in September or October, but the eggs overwinter and the larva do not hatch until the following spring. Hatching is strongly influenced by environmental conditions such as temperature (at least 17 °C) and humidity. Females prefer to deposit their eggs on solid substrates at warm and sunny sites. Most eggs from one ootheca hatch at the same time along the entire convex site, as worm-like prelarvae. The hatchings always occur in the morning.
