ootheca

About 3-4 weeks after mating, the female will make her first ootheca.

Up to 90 black and red nymphs may hatch from a single ootheca.

The protective capsule and the egg mass is called an ootheca.

About 200 nymphs will hatch out of a normal ootheca.

Others are less discriminating in their host choice, and will attack almost any ootheca of a particular size.

These hatch in approximately six weeks and contain thirty to fifty eggs per ootheca.

Each ootheca produces up to three hundred nymphs when it hatches.

This species can lay around 4-6 oothecae with a period of 4-6 weeks in between each ootheca.

Two weeks after mating, the females lay egg cases known as ootheca on twigs and branches.

This mantis breeds rapidly, with females able to lay an ootheca every 3 to 4 days.

Depending on the species, the ootheca can be attached to a flat surface, wrapped around a plant or even deposited in the ground.

The female can produce several spherical ootheca roughly the size of a table tennis ball, containing up to 400 eggs.

Females produce an egg case (ootheca) which protrudes from the tip of the abdomen.

Female produce an ootheca within a few days of mating and can produce several before she ends her life cycle.

The eggs lay dormant over winter, and if they survive, nymphs will start emerging from the ootheca in early spring.

An ootheca usually contains many eggs surrounded by a foam of protein which may then harden into a tough casing for protection.

Females carry the ootheca (egg case) internally, and release the young nymphs only after the eggs have hatched.

Once the ootheca is extruded it is deposited in suitably moist leaf litter.

There is no ootheca diapause.

After laying the ootheca the female sits on her ootheca to defend it.

Often during or after mating the female S. californica devours the male, allowing the female to have enough protein to create an ootheca.

A single egg is laid per ootheca, into a host egg in some Evaniidae, and between the eggs in others.

During fall, praying mantis females deposit an ootheca on the underside of a leaf or on a twig.

Individual T. elegans hatched from a single ootheca and reared under the same conditions can show color variation between tones of red, green, and yellow.
