Mantid Ootheca (Egg Case)

Natural Habitat

Found attached to twigs, stems, walls, or fences in gardens and wooded areas.

Diet & Feeding

The developing nymphs do not eat until they hatch; once hatched, they are carnivorous, eating any small insects they can capture.

Behavior Patterns

The female produces a frothy secretion that hardens into a protective, papery case called an ootheca. It protects the eggs from predators and freezing temperatures through winter until spring hatching.

Risks & Benefits

Highly beneficial to gardens as they hatch into hundreds of praying mantises that act as natural pest control. They pose no risk to humans.
