I have seen these at my house at least four times in the past eleven years. They have been on the driveway or walkway after a rain. I kept the first one in moist dirt in a baggy but it died.
The distal end is bifurcated with grippers. The proximal end is smooth and probing.

Horsehair Worm

Gordian Worm

Hi Laurie,
Thanks for the detailed coordinates, but we haven’t a GPS device to get a named location.  Seems like we are probably talking San Luis Obispo, California.  This is a Horsehair Worm or Gordian Worm.  It is an internal parasite that preys upon Potato Bugs and other Orthopterans.  We have also received reports in conjunction with Camel Crickets and Spiders.

Location: San Luis Obispo, California
