Even though this is a non-native species, I hear that some states like Connecticut, recognize it as an important species and protect it. I find that bizarre.
Unlike pond dragonflies which continue to patrol their territories back and forth, forest dragonflies are more weary. Try not to miss your chance. If you scare them too much while photographing them, or when trying to capture them, they will fly to the tree tops and just sit there till you leave. Luckily there were several of them, affording us multiple opportunities.
