Dragonflies are, bar none, the most agile and skilled fliers in the animal kingdom. No other animal can fly forward with great speed, hover and turn in place, and most impressive of all, fly backwards. The muscles that control their wings are like pistons, incredibly strong, and they can independently control the angle of each wing. Their flight patterns are being heavily studied for use in designing drones, and were the explicit inspiration for the animation of the ornithopter wings in the new Dune adaptation.
Dragonfly nymphs spend their larval years underwater. And yes, I do mean years. They spend most of their lives in this juvenile, aquatic state, up to five years in some species, hunting mosquito larva, tadpoles, even small fish as they grow. They don't undergo a true metamorphosis; they moult, shedding their exoskeletons to grow, and eventually reach a point where they climb up out of the water onto a plant well above the surface, and moult one last time. Still clinging to their exuvia (shed exoskeleton) the imago pumps their wings full of heamolymph (bug blood) for the first and last time, spreading them out into the gloriously agile appendages that will carry them through their brief adulthood.
Adults will anywhere from a week to six months on average before they die, depending on species. They have incredible eyesight as well. Those gigantic peepers can see in nearly 360 degrees above and below it. And they see with precision. It used to be thought that insects had poor vision with their compound eyes; more recently it's been found by rapidly making each photoreceptor at the end of each lens go in and out of focus they can assemble a very sharp picture of the world, much as we put together a complete picture of our surroundings from constructed memory of all the spots that aren't the tiny area our pupils can actively focus on. The end result is that these guys can see pretty much everything happening around them in great detail, which they combine with their incredible flight abilities to snatch up and eat their prey directly out of the air.
Dragonflies can be fiercely territorial, protecting the best spots for finding mates and laying eggs. When it does come time to lay eggs, they usually lay them on plants that are directly on or even under water. The nymphs will hatch and start preying on whatever they can find and the whole thing starts again.
Dragonflies are beautiful creatures and it's mesmerizing to watch them fly. Keep an eye out if you're ever near a body of water. They're probably there, being magnificent.
Fun fact about dragonfly nymphs:
ShowYou see that appendage at the bottom of their heads? That's called a mask, it's a sort of mandible that's adapted to unfold and snag prey.
Yaaaaaaay bugposting is back! I never knew they spent so long in the larval stage compared to adulthood! I love dragonflies because, like cicadas, they're a harbinger of summer and, therefore, summer holidays.
Some of my earliest memories are of sitting by the small fish pond at my grandma's house watching dragonflies flitting expertly around the garden as the drone of cicadas reaches a fever pitch in the warm, early evening.
Probably one of the reasons why one of my favourite Pokemon is Flygon (Vibrava is the other dragonfly Pokemon, but, kinda not as cool imo).
I was feeling incredibly sad and lonely at 2 AM and remembered that telling other weirdos on the Internet about bugs made me happy, it's a better use if time than hating myself and despairing of ever connecting with another human being
I'm glad that talking about bugs helps distract from, if not alleviate, some of that loneliness. For my part I definitely enjoy the few minutes of repreive won from reading about cool insects. Thanks for putting these out there.
Honestly they're so obviously one of my special interests that i think it's only because of internalizing 4chan toxicity I resisted a self-diagnosis for so long
Normies don't like to learn this much about bugs and go tell other people about bugs and hoard pictures of bugs and write about bug people
These are one of the few flying bugs that don't trigger my PTSD, I love these guys. They're so beautiful!!
I don't even live near a significant body of water and see them all summer long. Just the couple of agricultural ponds in the area must be enough for them? Idk, but it's great that we get so many of them, they're such a delight. ❤️
We have a pond and there are so many different species in all different beautiful colors, I love it. Precious lil things. I saw one snatch a bug right out of the air and eat it. That was cool.
Excellent post.
They are some of the most successful predators on the planet, having a 95% hunting success rate despite specializing in catching prey in midair.
Also, they can't walk. They have strong legs but don't use them to walk, the adults have to take off to move.
Dragonflies are a 5/5 bug
Cool name, cool aesthetic, very fast and agile, eat mosquitos, not a pest
