Saw this posted over at Expo, a good slide show of bugs you may encounter in the backcountry.

Very informative. Thanks for the post. I will add this since it did not go into much detail with the black widow. If a full grown adult in good health gets bit by a black widow you should get medical attention quickly but if that's not possible don't panic you will more than likely survive. I myself have been bit several times by the black widow and only once have I gone to the hospital. The symptoms that follow a bite are extremely uncomfortable but you can get through them. If a child or senior gets bit drop what you are doing and get them to a doctor ASAP! For a child or senior these spiders can be deadly.

 

Corey: thanks for finding that and posting.
good info to study
