Entomology (Study of Bugs)/spider identifiaction


Can you please help me identify this spider?  I think it maybe a 'wolf spider'? Large 1 1/2 to 2 inches leg to leg. Found inside - released outside - Clemmons NC.

Thanks - Dennis

Dear Dennis - Yous spider is in the family Pisauridae (fishing/nursery web spiders); it appears to be Dolomedes tenebrosus, known as the dark fishing spider. In spite of that name, these spiders often wander far from any open water source. They are closely related to wolf spiders, differing primarily in not having eyes as large as those of wolf spiders. See http://tinyurl.com/af762wl for images and more detailed information.
Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
