Wow, that was a thorough guess! Your first answer is correct. Some of the ways to recognize a Dark Fishing spider are: The orangey band markings on the legs and the row of black M or V marks on the abdomen. The easiest way to tell it from a Wolf Spider is that Fishing Spiders have pointy “butts” and the Wolfs have round posteriors.

That’s right! Fishing spiders also tend to lay flatter, and have a more spread out posture 🙂
