Topic: Ootheca

	German Cockroach
		The ootheca is approximately 8mm in length by 3mm in width, which in relation to the female is large.
		The ootheca shows a sequence of colour changes, from a pale white in the early stage, through a pink colour after a few hours, then to a light brown before becoming a deep chestnut brown after a day or so.
		The ootheca is carried for an average of ten days, although this incubation period may be shortened by a day and a half for each degree F rise.

		The ootheca is formed in the female and as it exits it is stamped into shape by the ovipositor valves (rather like a snackwich maker gives toasted bread those troughs and ridges), and hardens on being exposed to air.
		The female carries the ootheca round on the end of her abdomen for varying lengths of time before dropping it on the ground or glueing it to something.
		The ootheca is produced inside the female but instead of being laid, it is retained in a uterus or brood sac where the eggs develop.

	Gordon's Praying Mantids Page
		The eggs are produced in an egg case called an ootheca this may produce 30 to 300 young mantids depending on the species.
		The ootheca is a sort of polystyrene egg box which is secreted by the female as a liquid and then whipped into a froth around the egg cells, it varies in structure between species.
		The ootheca provides some protection against the environment and hides the eggs from many predators, however many are still parasitised by members of the Hymenoptera Parasitica, whose long thin ovipositors allow them to lay their eggs inside the cells hidden within the hardened foam of the ootheca Hatching usually takes between 3 and 6 months.

		The ootheca is usually dropped or attached and glued to some surface in a sheltered area near a food source within a couple of days following its formation.
		Members of the family Blaberidae have the ootheca briefly protuding during its formation, they then retract it into a brood sac, incubate it, and when the eggs are ready to hatch it is again extruded.
		The nymphs free themselves as the ootheca is forced from the brood sac and drop to the surface giving the appearance to live birth.

		These roaches have relatively recently on the evolutionary scale begun to retain their ootheca (egg case) until birth rather than deposit it immediately for external incubation.
		The function of this behavior is unknown, but it appears as if the female is almost 'air drying' the ootheca before retracting it into her body.
		Such behavior is quite common and the ootheca nearly always subsequently carried to term except in cases of environmental stress, illness, or malnutrition.

		The ovipositor is not visible, and eggs are usually laid in a purse-like ootheca, an egg case produced in the female's reproductive system.
		Some species carry the ootheca protruding from the end of the abdomen until just before the eggs are ready to hatch.
		Some retain the ootheca inside a chamber within the reproductive tract until the eggs hatch, and then the young are born alive.

		The ootheca is made up of a liquid substance which the female whips up in to a foam, she will deposit her eggs in this foam which will quickly harden in to something which resembles polystyrene.
		The newly deposited ootheca can remain in the main tank for around 3 months or until the first signs of hatching can be seen, this can be between 3 and 6 months depending on species.
		Once the ootheca begins hatching and the hundreds of tiny mantis emerge you have two avenues you could take.

		4.I've read that on a few websites that it is better to let ootheca hatch in a larger tank and keep all the nymphs together due to it being easier to keep humidity up in a larger tank for the nymphs.
		If you mean that the ootheca are infertile and never hatch, the chances are pretty high, unfortunately.
		I've had Chinese mantids lay as many as 7 oothecae, and carolina mantids lay as many as 5, but in order to insure all are fertile I would mate the female again after she lays 3 oothecae

		When the outer shell of the egg case (ootheca) are completely formed inside of her brood pouch, the mother Hisser extrude about the ¾ inch the ootheca (not the entire length of ootheca) outside of her body as if she is “air drying” it.
		The width of the abdomen of a Hisser is wider than the thickness/height of its body, so, it is much easier for her to store her ootheca inside of her brood pouch in “horizontal” direction, once each egg is formatted in the same hight with proper numbers inside of her blood pouch.
		Needless to say, for Hisser babies to wiggle out from the each egg of ootheca, it is absolutely necessary for the ootheca to be placed inside of mother Hisser horizontally; otherwise, baby hissers can not come out in orderly fashion if not they can not come out at all from their each egg case.
