Saw an Eastern Pine Elfin today, first of year, and it's been several years since I saw any at all. Not a rare butterfly by any means, but a good sighting nonetheless. They're small and inconspicuous (only about 1cm long, blackish when on the wing), and they never stray very far from their trees. I stalked it for a while until it let me get close enough to take a cell-phone pic.
I only had the phone because I wanted to get my mileage, but that was a fail. Apparently if you start moving before you get a GPS fix, it never locks in.
