Running Crab - NH 217


NH 217
Running Crab Spider
Philodromus sp.
Category: Arachnids
Family: Philodromidae

Spider Saturday is back! And to start off a summer of spiders, we have this guy who is a running crab spider of the Philodromus genus. It's a fairly large genus with hundreds of species, so we can't be positive of what species this guy is unless we took a look under the microscope. This guy was found on May 29, 2011 in Cass Park, Ithaca, New York. 

I don't have too much information about these guys at the moment, though I'll try and look up some more information next time I go to the library as there is only so much information I can dig up on the internet. These philodromid crab spiders do not have webs though some will use silk as a dragline. This particular genus is generally flattened and you can see some visual aids in the identification process of Philodromus spiders here. And as you can see from the photo these spiders tend to have few, if any, hairs/spines on their bodies (known as setae).
