What are the characteristics of mantis nest?

Mantis has no nest, only an egg sheath. During the spawning period, most species gradually enter the adult stage in mid-July every year, and begin to mate in late August. Female insects choose branches or walls, fences, stones and cracks to lay eggs.

When laying eggs, the left accessory gland secretes foamy protein substance at the opening of reproductive cavity, and the right accessory gland secretes diphenol, which is immediately oxidized and awakened, so that the secreted protein substance solidifies into a hard shell to cover the egg mass and form an egg sheath. The number of egg sheaths, the size of egg sheaths and the number of eggs in the egg sheaths of a female locust vary with different species. Generally, it can produce 1~4 egg sheaths.
