Explanation of Names
Dolomedes albineus Heinz 1845

Identification
Generally an ID can be made by the white band along the 'face' (clypeus):

D. albineus is also the only member of the North American fishing spiders to sometimes sport a mossy-green coloration on the abdomen.

D. albineus often has coarse hairs on the legs and abdomen that stick out perpendicularly to the legs/abdomen, giving the spider a bristly appearance that is not observed in other Dolomedes species in BugGuide's range. However, this feature is not always present.


D. albineus one other useful feature is the head (cephalic) region of the cephalothorax is raised above the rest of the cephalothorax.
Range
e. US to c. TX (BG data)
Habitat
Often observed on trees or on walls of manmade structures. Both D. albineus and D. tenebrosus are often observed away from water, unlike their relatives in the genus.
