Dolomedes sp.? fishing spider - Dolomedes
Payson / Allendale Spring, Adams County, Illinois, USA
May 23, 2018
Found on outdoor couch near flowing springs and seep area. Feel pretty sure this is a Dolomedes but I'd not seen this much white before. Does tenebrosus occasionally have this coloration?

Bold white coloration on the sides
can be found in several Dolomedes species.

D. tenebrosus
D. vittatus
D. scriptus

Doesn't appear to be D. vittatus (no extremely conspicuous dark cloven-hoof-shaped mark in the center of the cephalothorax) or D. scriptus (this doesn't have a complete carapace stripe, nor is the W-shaped patterning on the abdomen well-defined). In addition, while browsing through guide images for these species, I've only seen that specific shape of white patterning on the abdomen in D. tenebrosus.

However, this has a juvenile look to it, which may affect things - most of the guide images are of adults.
