Wolf Spider Defense...

Ok i was on my driveway the other night and saw what i thought to be a Wolf Spider.. Then I touched it and then it turned around with its 4 front legs high in the air and revealed its fangs is this normal?

Your spider might also be one of the Mygalomorph spiders. Here's a photo of the behavior you describe here

Not sure what normal is...
but I've seen jumping spiders do this to eachother, I assume they were warning eachother to back off.

 
this spider was huge
how large do jumping spiders get? this one was about as big as a silver dollar

 
The spider I saw
doing that was a Phiddipus audax, they get to about half an inch. I may have been misinterpreting the action, though. This is the same thing they do when they are 'displaying' for the female. I didn't get a good look at the other spider (on a chain link fence) so I'm not sure whether it was a female or another male.

 
Believe this is common
I've seen species of most spiders rear up with front legs in the air and fangs exposed in response to some form of surprise/disruption/harrassment. Some are more easily agitated than others--I used to have a tarantula, and he did perform this behavior but it was rare to see.

Generally it is a warning/threat display.

 
Ya
i was thinking a warning and the spider was about half the size of your regular tarantula i got him on video if you would like to see it i can upload it..
