Dark Fishing Spider
Dolomedes tenebrosus
- Order & Family
- Araneae/Pisauridae
- Size
- Leg span can reach up to 3 inches (approx 7.5 cm), with body length around 0.5 to 1 inch.
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.
