Interesting bunch of feeding photos.
Jeff, you must have found the cafeteria. The "ball of flies" series is the most impressive of a great bunch of posts.

Thanks
Thanks Ron. The robber flies make it easy. There is an abundance at this preserve at this time, as well as an abundance of prey items. As you walk on the path, scads of hoppers and tiger beetles fly off and provide opportunities for the flies. You can hear the flies and track them to where they land.
