Anyone who lives in the southeastern US has probably encountered fire ants and anyone who lives elsewhere in the US has probably heard of them, but you've probably never gotten a close look at one. Many people use the term "bites" for what fire ants do when you disturb them, but really what they do is sting. They do bite, but only to gain leverage to stick their stinger into you--the bite itself does not hurt. I'll try to get an image up of a fire ant's stinger, but I think that these will do in the meantime.
