Fast spider with numerous young on its back. Body was about nickel size or slightly larger.. Updated 4 June 2012 with spider on leaf.
Art, there is no maximum number of missions you can join but you can currently only add a spotting to 5 missions.
This is likely to be either the rabid wolf spider (rabidosa rabida) or the dotted wolf spider (r. pauctulata) but because it is almost impossible to be certain of the exact species without being able to see the abdomen I suggest you title this "wolf spider" & use the family name "lycosidae" in the scientific name box.
If you still have doubt, take a look at look at the third photo half way down the page. Spider carring its young. An exact Match.
Great spot Art!
You might like to add this to the Brooding Behavior in Arthropods mission!
