Hummingbird, NO; Moth, YES
This hummingbird moth is fascinating. He is feeding on the nectar of Wild Bee Balm or Oswego Tea (Monarda). I have seen several at River of Life Farm in 2008 and 2009. Since I am always watching for hummingbirds, these always catch me by surprise. They are fairly common, however.
Next time you see a hummingbird working some flowers at ROLF, look again and see if it is a Hummingbird moth.
