Fishing Spider - Dolomedes instabilis

Family Pisauridae  

This page contains pictures and information about Fishing Spiders that we found in the Brisbane area, Queensland, Australia.
 
Leg to leg 50mm
 
The Fishing Spiders have long and strong legs, all legs about the same length. They usually seen resting on water edge with some legs touching the water surface. We believe by touching the water surface the spider can detect if any prey is approaching.

They move freely on water surface, and sometimes submerge to catch small fish, tadpoles and water insects.
