Anasaitis canosa, the Twinflagged jumping spider;
Lowndes county, Georgia (02 September 2012).
A wee scamper, this Twinflagged jumping spider made me work hard to get this shot — the clearest I could manage. The spider kept darting left and right, forward and back — wash, rinse, repeat. Jumping spiders are tiny little explosions of seemingly perpetual energy.
