Praying Mantis hatch report - Day 361

    About Praying Mantis Eggs

    Praying Mantis

    The male deposits his sperm in a special chamber in the female's abdomen. She then lays up to 400 eggs, depending on the species, stashing them in a frothy mass that hardens into a protective capsule called an ootheca. This capsule can be attached to a flat surface, wrapped around a plant or left in the ground.

    The young mantises take their cue to hatch from their environment. When the conditions are correct, one or two pronymphs, which is the first maggot-like stage of a Praying Mantis, will wriggle their way out of the ootheca. Hundreds of their siblings will follow.

    The pronymphs will almost immediately moult into nymphs, which look like miniature adults, by shedding their skin. The nymphs will then rest for many hours as their new bodies harden.
