Natural Habitat

Commonly found on trees or vertical structures like walls, often away from water, despite being a 'fishing' spider species.

Diet & Feeding

Carnivorous; feeds on a variety of insects, other spiders, and occasionally very small vertebrates.

Behavior Patterns

Mainly nocturnal hunters that do not spin webs to catch prey. They utilize vibrations to detect movement. High levels of parental care involve the female carrying the egg sac in her chelicerae until hatching.

Risks & Benefits

Benefits the ecosystem by controlling insect populations. They are not aggressive toward humans; while their bite can be painful (comparable to a bee sting), they are not considered medically significant unless the individual has an allergy.
