White-banded Fishing Spider, Aransas National Wildlife Refuge, Tivoli, Texas September 2019

While all the other species in this genus are semiaquatic, the White-banded Fishing Spider (Dolomedes albineus) stands out as the only arboreal member. The first part of the binomial is Greek for wily or deceitful. I imagine it has something to do with their freaky ability to walk on water (thanks to the hydrophobic hairs that cover their bodies). Some of the species have a leg span of three inches and are known to capture small fish.
