I live in So Cal...so i just got bit by one of these tonight and was online looking for what it could have been. At first i thought it was a brown recluse and got terrified. it pinched the bottom of my foot and hurt bad. it started itching and then slightly burning but only lasted less than an hour. i soaked my foot in hot water for about 5 min. and then put ice on it. it has been over 3 hours and i feel fine and the pain has gone away. there is no apperance of the bite/pinch. hope this helps anyone who got bit and is freaked out as much as i was. From what ive checked i don't think these are very harmful. just watch where your stepping. :)
