Growing up I was terrified of these creatures that we called darning needles. Stories were passed from kid to kid about your lips getting sewn shut. Swearing might have been required to invoke the sewing activity but I never saw any kid so inflicted.
Now I know that the dragonflies eat bugs so I’m happy to have them around. The ones we see in South Carolina are much prettier than the ones I remember in Maine, but that may be a trick of time.
Sometimes they land right on the duck weed but more often take advantage of the other pond plants.
