Natural Habitat

Commonly found on the exterior and interior walls of buildings and around window sills in tropical and subtropical regions.

Diet & Feeding

Carnivorous predator; feeds primarily on small insects such as flies, gnats, and mosquitoes that land on vertical surfaces.

Behavior Patterns

Active diurnal hunters with excellent vision. They do not build webs to catch prey but instead stalk and pounce on it. They are known for their 'dancing' courtship displays and use silk as a safety tether when jumping.

Risks & Benefits

Generally harmless to humans and not aggressive; their bite is rare and usually less severe than a bee sting. They are highly beneficial for pest control as they consume common household nuisance insects.
