The timing is about right. It might of interest to note that of all the winged insectivores the bat is judged to be the most efficient predator of all, including swallows and dragon flies. I recall reading that their technique is somewhat like that of some whales, in that they 'scoop' the air and simply filter out their catch as opposed to catching individuals. So put up a bat box in your yard...

Good spotting! Never leave your bins at home.
