Running Crab Spider / Philodromus
This is a running crab spider - technically a member of the Philodromidae family of spiders. These are found pretty much everywhere in the world.
We believe that more specifically it is a type of running crab spider called a Thanatus from what we can tell!
It is less than an inch in diameter. It was found on our back porch in Sutton.
Apparently the reason spiders have those "dimples" on their backs has to do with their internal organs. They don't have a skeleton. The way organs are held in place are with thin "guy wires" which attach to various parts of their body and then support the organs. So those dimples are one of the internal attachment points for a wire, that is holding up an internal organ.
