The common whitetail dragonfly can be seen hawking for mosquitoes and other small flying insects over ponds so I’m happy I have a bunch of dragonflies eating my bugs. But I’m also glad they aren’t as big as they were 325 million years ago when they had a 30 inch wingspan as that would be a little nerve–racking with as many as I see flying around my pond.
