A not so itsy-bitsy-spider was climbing the walls of the house yesterday and later found exploring the front porch. Not yet sure what he is, but have a query in to the Arthropod Museum curator at the University of Arkansas. Toe-to-toe, this fellow was about the size of a quarter. He was also missing a leg, which made his climb harder. During one of his slow climbs, he fell off the wall, but got back up again.

Thanks to the entomologists at the U of Arkansas campus in Fayetteville, we have an ID for our mystery man:

“That is an adult male Myrmekiaphila, the only eastern genus of Euctenizidae, the ‘wafer-lid trapdoor spiders.’ The name ‘Myrmekiaphila’, meaning “ant-loving” refers to fact that early authors found burrows near ant nests … although there is no actual association with these spiders and ants. Males reach adulthood in the fall and early winter, when they leave their burrows and wander in search of females (which remain in their burrows). The strange modification of the first leg (metatarsus) seen in these photos is used to grip the females forelegs and push her backwards awkwardly, which prevents her from eating him during mating.”
