Need Identification Help on Spider
Dear Bugman,
I was wondering if you could help me identify this particular spider. I live in Northeast Texas, about 10 feet off of a river. I at first thought it was some sort of wolf spider but its coloring was not the brown I am used to seeing. The silver color really jumped out and caught my attention, especially against the brown background. I can’t imagine this sneaking up on anything! J Also, does his stance (4 front legs together and forward) imply anything or is he just resting? Thanks for your time and help.

P.S. The board he is hanging out on is a 2×4 underneath my porch.

Hi Gina,
You have a fishing spider from the genus Dolomedes. These large spiders are usually found near water and are capable of catching small fish. I’m guessing your species is Dolomedes albineus, commonly called the Whitish Dolomedes. “This is a large species,” according to Comstock, “closely allied to D. tenebrosus. The female is easily recognized by a yellowish longitudinal band edged with black on the ventral (ed. note: your view is dorsal) aspect of the abdomen. … This is a Southern species. Hentz states that it does not dwell habitually in caves and cellars, but is usually found on the trunks of trees, yet in dark, shady places.” The stance appears to be a resting position.
