Now after walking 20 meters with the damselfly on the finger, I wanted to put it down in the grass again, but there I noticed some small flies sitting on the grass. I slowly moved my finger with the damselfly on it toward a fly, so that the damselfly was pointing toward the fly, and when the distance wwas about 4 centimeters (about 1,5 inch), the damselfly abruptly "jumped" foreward and grabbed the fly with its mouth.
I guess this is as close I will ever get to hand-feed a damelfly
