Diet & Feeding

Omnivorous; feeds on a variety of matter including decaying organic debris, smaller insects, and garden plants like flowers, vegetables, and seedlings.

Behavior Patterns

Nocturnal insects that are active at night and hide in crevices during the day. They are known for their maternal care, where females guard eggs and young nymphs. They use their cerci (pincers) for defense and capturing prey.
