Comments & ID Thoughts

Any idea what kind of spider this is? Wolf Spider? It's carrying a sack underneath when I thought wolf spiders carried there eggs on top.

This is a female Fishing Spider. I think she’s Dolomedes tenebrosus. Fishing Spiders carry their egg sacs under their heads. Wolf Spiders carry them under their back-ends. This helps to protect the eggs from predators including parasitic wasps that put their own eggs into the egg sacs so their larvae can eat the spiders eggs or larvae. The abdomens of Fishing spider end in a point, Wolf Spiders have a more rounded posterior. Both will hunt in water and without webs.
