  • [Music] Okay, today we're going to try to figure out how wagon...
  • Today we're going to try to figure out how dragonfly wings work So Phil has a dragonfly that I caught last night on our night walk, and we have a high speed camera, and we are set up with a macro lens to try to collect that exact spot.
  • So tell me when to trigger.
  • (Phil) Let's go. (Destin) You got it?
  • (Destin) Holy cow. - Looks cool, doesn't it?
  • - Oh man. - Yeah?
  • - We got it. - Awesome.
  • [Music] (Destin) Alright, so you have one of your entomology books here?
  • - You know it. - Which book is it?
  • - Borro and DeLong's Intro to the Study of Insects.
  • This is a classic entomology book.
  • So with these guys the muscles are actually pulling directly on the base of the wing.
  • So it's a direct flight mechanism. Um... - So what's an indirect flight mechanism?
  • - Indirect flight mechanism, it actually just pulls on the body wall of the thorax and the collapse or expansion causes the wings to then move.
  • - So we're going to go from the rainforest to a rainy day in my home town.
  • Now, we have all different kinds of art projects here and the one I really want to show you is the dragonfly project.
  • What they've done is they've given metal dragonflies to all the different organizations in the town and they let them paint them however they want.
  • What I think is cool about the dragonfly is that the wing attaches to the body in a completely different way than most insects.
  • To explain this I've decided to become a dragonfly muscle.
  • This is a wasp.
  • To see how normal insects operate their wings we need to cut the thorax in half so we can see the muscles operating on the inside.
  • Eeugh, it's uglier than I thought. Anyway, The wings of most flying bugs use this method, which is called indirect musculature.
  • The muscles pull on the body wall of the thorax instead of on the wing itself.
  • The shell then pushes on the wing, which seesaws on a pivot point and moves up and down.
  • The problem is muscles pull - they don't push.
  • So how does the wing return?
  • If you would've imagined that the thorax was shaped like a football, the big muscles would be squishing the ball in on the middle.
  • When you turn it on its side you can see that this little muscle runs the length of the football and pulls in longways from the inside.
  • This makes the middle bulge back out, which moves the wing down.
  • Dragonflies, however, operate differently.
  • When we look inside a dragonfly we can see that they have what's called direct musculature.
  • Their muscles pull directly on the wings and are able to operate each wing independently in both directions.
  • This is a big deal, and this is why completely dominate the insect flying world.
  • If you look back at the high speed, in those little cracks you can see muscles wiggling and pulling directly on the wings.
  • That's pretty awesome, huh?
  • (Phil) So, they say "in many Odonata," which are dragonflies, "the front and hind wings move independently, and there is a phase difference in the movements of the two pairs; that is, when one pair is moving up, the other pair is moving down.
  • Okay, Dr. Jim Usherwood in the UK and his colleagues discovered that because dragonflies have two sets of wings, for the most part they're inefficient.
  • More inefficient than just normal insect flight with two wings.
  • They made a robot with two pairs of wings and they would vary the timing between the two, and they found that at a certain timing they could get 20% more efficiency than they could with just two wings.
  • Dragonfly wings have something on them called the pterostigma, which is latin for "wing mark".
  • You may have seen them before. This is a dark cell on the leading edge of the wing that's heavier than the rest of the wing.
  • At a certain velocty, thin wings begin to automatically vibrate, which makes it impossible to glide quickly.
  • With the added weight at this particular spot on the wing, these vibrations don't start till a much higher airspeed, which means dragonflies can now move much faster.
  • Turns out it's a complex aerodynamic structure built right into the design of the wing to help them glide.
  • Every time I see a dragonfly I always try to spot that spot.
  • Wait a second, have you ever seen a dragonfly glide?
  • Okay, in this last video you can see that we're in a canoe, we have a Phantom Miro high speed camera and we're trying to capture these dragonflies as they lift up off the grass.
  • Now, you cool thing about it is you can see that he uses his wings to hover, but he also uses them as a way of gliding.
  • It's incredible, 'cause can see him feather the front wing and allow it to glide the air over the second wing.
  • I've never seen anything like this. Check it out.
  • [Music] So I hope you learned something along with us about dragonfly flight.

  • Okay, in this last... [Train nearing] There's a train. It's loud everywhere here.
