I live on a lake with many types of dragon flies.  Because I was raising
Queens at this place I checked as many of the possible problems of losing a
virgin queen.  I used a water gun with soap in it to gather dragon
flies(certified dragon slaugher).  I didn't found any bees in the stomach.  I
have Great Crested flychatchers nesting, Balitmore Orales, Kingfisher, Wood
Thrush, Purple Martins, Swifts,  many varieties of wood peckers and Wood
Ducks with babies all that are bug eaters.  I will gladly give up a few bees
to get rid of the misquetos.   The bass (size of the Loch Ness monster) in
the lake love the bees in the water.   Michael Housel
