Dragonflies are great predators of insects and therefore helpful to humans. We are going to need them this summer to clean up all the mosquitos in central and northern Minnesota! All dragonflies need water as a hatching ground, but once they hatch, many of them move to the meadows and prairies. We began to photograph them last year, and find them fascinating. This particular dragonfly is a female Widow Skimmer. Some dragonflies are very easy to identify and others are extremely difficult to key out. Our guidebook selection is growing.
