It's from the Genus Dolomedes. In fact, that species has sexual size dimorphism meaning the males and the females look alike, but there is a size difference in the male and the female (females being larger). They also have a common name of nursery spider (because of the web it builds) or fishing spider (because they live near water). When the female is about to hatch her egg sac she builds a nursery web and guards them. A wolf spider is a common name for the Lycosidae genus. They are a beefier spider that get their name because they run along the ground and when the females egg sac hatches, the babies catch a ride on the mothers abdomen.
An interesting fact about them. They have hairs under their abdomen that will hold an air bubble as it goes under water. It can actually access this air bubble and breathe under water. They have book lungs so they breathe a little different that those with lungs.
Both beneficial spiders that eat things you dislike even more...or should.
I started to take entomology in college but dropped out. Now it's just trivial info swimming in my brain.
