Diet & Feeding

Feeds on various insects and other small arthropods that get caught in its web.

Behavior Patterns

Builds irregular, tangled webs, often in sheltered locations. Females are known for their spiky egg sacs. They are generally shy and not aggressive unless provoked or defending an egg sac.
