Natural Habitat

Commonly found on vegetation, tree bark, and the exterior of buildings or vehicles; they are frequent 'hitchhikers' on cars.

Diet & Feeding

Carnivorous; they are active hunters that chase down small insects like flies, gnats, and aphids rather than using webs.

Behavior Patterns

Risks & Benefits

Harmless to humans; they provide ecological benefits by acting as natural pest control for gardens and agriculture.
