Thanks Herschel.

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 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.

This robber fly was pretty he
This robber fly was pretty heavily infested with mites, wow. They never to cease to amaze me at the prey they take.

I never knew they were susceptible to mites until I started taking pics of them.
