Dragonflies are here in SE Michigan but there is not a huge variety. I am about 3/8 of a mile from the nearest body of water. Here I have perhaps 4-5 species on a regular basis.
But then again things like the big Green Darner or the damsel flies and things like open fields, meadows and such. The small water sources that dot the golf course that I regularly play on has a lot more in the way of variety.
That Green Darner has to be my favorite. They zoom around catching insects on the wing and anything that loves to eat mosquitos is okay in my book!!
