See this bug in the Encyclopedia

Natural Habitat

Common on exterior walls, fences, ceilings, and buildings in warm, sunny regions; often associated with human structures.

Diet & Feeding

A visual predator that hunts flies, mosquitoes, small moths, and other arthropods, usually without building prey-catching webs.

Behavior Patterns

Active by day, it stalks and jumps onto prey, using silk as a safety line. It may retreat into a small silk shelter and produces several broods in warm climates.

Risks & Benefits

Not medically significant to humans and generally nonaggressive. It benefits people by consuming nuisance insects; identification is approximate because markings vary among Menemerus species.
