The term "snake doctor" is used to refer to a dragonfly, particularly in the southern United States. However, there are many other words that can be used as synonyms for this fascinating insect. One such word is "darning needle," which is a term commonly used in the Midwest. In other regions, dragonflies are also known as "devil's darning needles" because of their long, thin bodies. Other variations include "mosquito hawk," "skimmer," and "kite." Many of these terms come from the dragonfly's ability to eat large amounts of mosquitoes and other flying insects, making them a natural predator and useful ally in controlling pest populations.
