Wolf Spider vs. Fishing Spider

Fishing spiders (Dolomedes) are often called 'wolf spiders' because of their size and hairy appearance. They are easy to separate on eye row geometry and habitat.

Summary

Fishing spiders have eight roughly equal eyes in two slightly curved rows and are nearly always found near water. Wolf spiders have two large 'headlight' eyes and three eye rows.
