Spidey wants to give you a hug!
This male jumping spider (family Salticidae) was performing his "courtship dance" for a nearby female. It didn't turn out too well, as the female quickly darted away after the male made a few attempts at copulating.
After battling with finding the ID, I got it down to genus: Lyssomanes
