Fascinated with nature at an early age, I spent a great deal of time in my formative years inspecting insects. Those most readily available and easy to catch were crickets, grasshoppers and sow bugs. Among those not so easy to catch were dragonflies and back in those days, nobody I knew wanted to catch one anyway. There was a reason for that.
None of the other kids from my neighborhood called them dragonflies. They called them “darning needles” or “sewing needles” because it was rumored that they had the ability to sew your eyes, ears or mouth shut. While I may not have fully believed that story as a lad there was probably a time or two when, if I did happen to see a dragonfly while outdoors, I kept a wary eye on it until it flew out of sight. Over the years, as my outdoor horizons expanded, my interest in dragonflies also grew and I discovered that, like all creatures of the wild, the Good Lord saw to it they came equipped to take care of themselves. For example, they do have incredibly sharp mandibles, but use them only for capturing prey, not to sew little boys eyes and ears shut.
|Truth be told, all dragonflies, like the Whitetail seen here, are no threat to humans.|

Despite the delicate look of a dragonfly's gossamer-like wings, they provide it with maneuverability unequaled in the insect world. They possess two pairs of wings, and can operate each wing independently of the others. They can fly forward, backward and even sideways and hover in one spot for an indeterminate amount of time. This unique trait in the flying insect kingdom is one of the primary reasons they are such skillful and stealthy aerial hunters.
|The dragonfly's bulbous eyes give it outstanding vision.|
A dragonfly's field of vision is nearly 360 degrees, with its only blind spot directly behind them. Their compound eyes consist of 30,000 facets – or “smaller eyes” each of which provides information regarding the dragonfly’s surroundings. Combine their extraordinary vision with their flight skills, and you have a predator that can either intercept or ambush its intended prey in mid-air without slowing down and, thanks to those sharp mandibles, consume it while still on the fly.
|In this instance, the hunter became the prey.|
Despite their being skilled predators, likewise the dragonfly is preyed upon by a number creatures including but not limited to fish, birds, mammals, reptiles and spiders. Pictured above is a Black-and-yellow Argiope spider wrapping a Red Skimmer in a silk cocoon for a later meal. Bon Appetit!
