Giant shield mantis (Rhombodera cf valida) nymphs hatch. They emerge with a black skullcap likely intended to protect the head as they push through the surface of the ootheca. Once out, the skull cap falls away, remaining attached to the harness that is part of the egg case which they then shed by splitting at the back and pushing out in a hunched position, much as they do in later life during a molt. The limbs, which looked like rubbery tentacles upon exit, become engorged with fluid taking their permanent shape once pulled from the egg case. I believe the bodily fluids are initially stored in the head, beneath the skull cap. Take notice to how swollen the head is until the limbs and body segments expand. There are several shots of a fully expanded nymph next to one just emerging. The length increase is quite noticeable.
Over 360 nymphs emerged over several hours from this single ootheca. I thought they would never stop coming!
I know this video is long but it's not intended to be entertaining so much as informative for those interested in this process.
