 | | However, the German cockroach carries its ootheca until 24-48 hours before the eggs hatch and the nymphs emerge. |
 | | Members of the family Blaberidae have the ootheca briefly protuding during its formation, 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 of live birth. |
