Out of left field, but do you have any sources on developing small riparian environments to promote dragonfly populations?
I recently learned that a popular anti-mosquito trick by painters in my area is to put a fake dragonfly on their cap. Which led me to wonder where the actual buggers have gone.
They're all in my yard, and I honestly don't know why. I'm almost half a mile from the nearest wetland. I think it's tall weeds. They seem to be like cats and want to perch on high spots.
My only problem is the invasive plants which are determined to overwhelm everything.
