The ootheca (egg case) of M. caffra is 12–30 mm long with rounded sides, soft creamy-brown, fawn or beige with a terminal handle-like extension. Hatching is not synchronised, and nymphs may emerge over a period of weeks or even over two seasons. Refrigeration of ootheca in the exotic pet trade can delay their hatching. [citation needed]
Mantis ootheca. Sang piao xiao or Sangpiaoxiao (Chinese: 桑螵蛸, [1] sometimes called Mantis Cradle [2] [unreliable source?] or Ootheca Mantidis [3] [unreliable source?] [4] in English) is a Pinyin transliteration referring to the oothecae, or egg case, of the praying mantis as an ingredient in traditional Chinese medicine.
The wasps develop in the reverse orientation of the mantids they share the egg case with. When depositing on a horizontal surface, a praying mantis will most often lay her ootheca on the underside, [1] so that when the mantises hatch, they are facing the earth and can utilize gravity to exit the egg and undergo their first molt.

Like all mantids, the California mantis is carnivorous, consuming virtually any other insect it perceives as small enough to be eaten, including other members of its own species. Males and females come together to reproduce but otherwise the adults are strictly solitary. Nymphs hatch in the spring from hard egg cases laid the previous fall.
Each ootheca usually contains 25-35 eggs, which hatch after 16–19 days. From hatching to adulthood takes about 2 months and 7 molts. Male adults live up to a month after their final molt, and are often able to escape unharmed after mating, rather than falling prey to the female as in the European mantis. [citation needed]
C. rhombicollis start life by hatching from an ootheca with 30-50 eggs. The first instars have very slim pronotums, almost like a normal mantis, but as they molt through life the hood will expand further from a hexagonal shape into a rhombus/pentagonal shape depending on the gender of the mantis. After the wet season, sometime after September ...
The egg of M. splendidus is roughly shaped like a prolate spheroid, with a slight anterior constriction and concave dorsal side. Eggs measure about 3.2 millimetres (0.13 in) long and 1 millimetre (0.039 in) wide. A U-shaped fissure from which larvae rupture the eggshell, known as the hatching line, is present at the anterior pole of the egg.
[63] [64] [65] In temperate climates, adults do not survive the winter and the eggs undergo a diapause, hatching in the spring. [13] As in closely related insect groups in the superorder Dictyoptera, mantises go through three life stages: egg, nymph, and adult (mantises are among the hemimetabolous insects). For smaller species, the eggs may ...
