Blue dashers are ornery, territorial little dragonflies that wreak havoc wherever they go. They terrorize not only each other, but also every other dragonfly nearby. This includes dragonflies that are twice their size. I love watching these little gangsters at work. I captured this little guy on the shore of Lake Telemark in Rockaway, NJ USA. I used the Nikon D3100 and the Nikon 85mm macro lens.
