It is believed that a fly’s life span is reduced by one third if they do not get the required amount of sleep!

Stacey Combes, a Harvard researcher who uses high speed cameras to study the flight mechanisms of dragonflies, stated that one dragonfly they were studying went through thirty flies in quick succession—and would have kept eating, if it had more to eat. After that, they’re free to chow down without any chance of losing their prey. They are active and fly about during the day and at dusk, but they become inactive and static overnight. The truth is, there’s an even deeper level of crazy at work here, as Dr. S.D. Lions, the shark of the land, are lucky to get their claws on a quarter of their targets. And while they may not have permanent dens, such as mammals do, to crawl into at night, they have learned to adapt and find safe spots for sleeping. Insects are very different from mammals, and their interpretation of sleep varies just a bit, too.

Other places you might find flies are fences, clotheslines, rafter in sheds or barns, even on electric wires.

Human eyes have three opsins—proteins that sense light—giving us a color range of red, green, and blue (one for each opsin). When a dragonfly sets its sights on a target, it will almost always end up with a meal.

Delicate yet powerful, each wing is connected to the thorax with a separate muscle group. In fact, flies get most of their sleep throughout the night. The Environment a Fly Lives in Effects Their Sleep, Where Do Flies Sleep? And once it catches its prey, it shows no mercy, because…. That example did serve a purpose though—dragonflies are incredibly efficient at what they do, bringing in close to 95 percent of the prey they set out to capture. Currently, she lives in Southern California where she enjoys all things outdoors. That’s because dragonflies are some of the most brutal killers in the insect world. They follow circadian rhythms of wakefulness and inactivity that function rather as sleep cycles.

The dynamics of capturing an object in mid-air are staggeringly complex, so much so that it’s usually something that’s only done by animals with complex nervous systems, like seagulls, or humans. The selection of a place to sleep also depends upon a few other contributing factors these include wind, rain, sun, and heat. Because unless you’re an entomologist, the answer is always the same: butterflies, dragonflies, and ladybugs—pretty and harmless, and infinitely unlikely to burrow under your skin while you sleep. Also crevices anywhere they can sit undetected. The video above perfectly captures the seemingly chaotic motion of a dragonfly’s wings as it ambushes a fruit fly. Keeping their prey in the same section of the grid helps with that incredible accuracy when they intercept something mid-flight. To intercept something moving with its own velocity, you have to be able to predict where it will be in the future. Where can I buy books, field guides, and other information about dragonflies and damselflies?

But give a dragonfly a chance to grow three feet long, and suddenly they don’t seem quite so harmless. Some creatures just have a will to live. While they wait for their new wings to harden, something that can take hours or even days, they are relatively sedentary.

But he’s not idle while he does this. Report from The University of Queensland – Flies sleep just like us! Ideally, a fly would like 12 hours of sleep. Acrylic on canvas 24" x 28" Exhibited at TN State University, Summer, 2005 Sold Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture. One of the most distinguishing features of dragonflies is the way their wings work. They live in the water, swim through the water, eat just about anything in the water (mosquitos, other larvae, tadpoles, worms, leeches, other dragonfly nymphs, etc. Aim the car so that the goat is in one square of the grid. It is that wonderful plant that provides the world with chocolate! Once those wings do fully develop, they are still relatively weak, so the dragonfly can only travel a few feet at a time.

(But please, don’t actually do that. Here’s a human comparison—draw a grid on the windshield of your car and pick a target.

This selective attention span allows the dragonfly to single out one target in a swarm, then zero in on it exclusively—while remaining aware of the the rest of the swarm to avoid a collision. Having to run, hide, or do anything to avoid getting eaten must be an extreme sport. And this includes both mammals and insects. Dragonflies with a shorter larvae cycle can even be found in simple rain puddles. A fly may also choose to sleep hanging upside down because there is no safe place on or close to the ground to sleep. Dragonflies do two things when they intercept their prey: first, their front legs curve up to cage it in, cutting off its escape. You can find dragonflies living and sleeping near freshwater sources often: ponds, lakes, rivers, swamps, etc.
