We see these critters around here now and again, but it's purely luck to spot one. They can be nearly invisible on some backgrounds. This one just happened to be on a partially downed pine tree that a few fence lizards tend to hang out on, so I always look for them when walking by. So I just happened to see this one on that pine tree bark.
