castianeira spider
I found this small spider underneath some stones in my back yard. It was with some small ants that
had a nest there.  I wonder if they knew they had an enemy in the midst.  © Carol Davis, 8-23-2008

ant mimic spider
I found this one in a window in a building in Springdale, Utah. I had to clean
up the photo a lot because they area was so dirty. Bugguide has a nice information
page showing many different species of
Castianeira.  © Carol Davis 3-29-2009
