The dragonflies are finishing up their chores for the season making sure there's a next season. They are very hard to catch, and pretty much impossible to catch in good focus, but I like them anyway.
Snail on a yucca, Punta Colorada Uruguay. There was a much bigger one but by the time I went to get my camera, change the lens, etc., it had descended more that half a meter into the grass below! Swift is not a word that I would normally use to describe a snail. My odds are on the Uruguayan racing snails in any race!
I took a series of these sitting on my front porch one evening this summer with a D800E and an AF-S 85mm f/1.8 lens. The shutter was at 1/2000, ISO 640, f/5. It was early twilight, the mosquitoes were starving and a battalion of these guys showed up to protect us. They fed for about 1/2 an hour and then disappeared leaving us mosquito-free. Dragonfly and prey.
