Well, maybe someone else can, but I have seen a few things where I am totally at a loss.
Here is one:
This is a dragonfly feeding swarm. There were somewhere between one and two dozen dragonflies flying within a foot or two of the grass. They fly fast, and there wasn’t much light. This photograph represents the best I got, and I took more than 30 pictures. I used the on-camera flash for this, but still did not freeze the motion.
Most of the dragonflies seemed to be the common green darner, but at least one was bright red–
it may have been a meadowhawk it was identified as a wandering glider (see comments).
I ran across a little information and a place to report dragonfly swarms at The Dragonfly Swarm Project, so I reported this one.
This is an amazing sight to see. The photos don’t do it justice.
