A wolf dressed in beach clothing

  

Eric found this amazing spider on the beach at Reid State Park in Georgetown, Maine, yesterday (15 September 2023).  Meet the Shoreline Wolf Spider (Arctosa littoralis)!

The spider blends in with the sand so well that sometimes it was hard to see the entire spider.  It was a little easier from the side, so here's that view:

 

 

And one more view looking down at the spider from above.  This perspective made me think of a kaleidoscope, with repeating patterns radiating outward:

 

 

 

Shoreline Wolf Spiders have a broad distribution, so if you're walking a sandy beach, keep your eyes open. This wolf spider is so well camouflaged that you may notice some movement across the sand before you realize that there is a predator hiding in plain view!
