Who is this little fellow with the silver legs and green eyes?
He was on the back porch under a dim florescent light, no moonlight, and the temperature was a warm, 72F. There had been a light rain during the day. The photo, without flash, washed out his colors so much that I enhanced them to get closer to his own natural gorgeousness. Not visible is that his legs appeared entirely silver and his wings are outlined in the same shimmering silver. The antennae and eyes are green. The head abdomen and thorax are the same turquoise, with blue shadows, as the wings.
Exquisite Little Winged One.

Dragonflies lack humans’ big brains, but they still get the job done, according to new research that suggests that these insects have brain cells capable of feats previously seen only in primates.
Specifically, the dragonflies can screen out useless visual information to focus on a target, a process called selective attention. The new study, published Dec. 20 in the journal Current Biology, is the first to find brain cells devoted to selective attention in an invertebrate animal.
Selective attention is crucial for responding to one stimulus among the dozens of distractions that clamor for notice at any given time, said Steven Wiederman of the University of Adelaide in Australia.
