    This is an interesting and easily digestible article that sheds some light on why and how (some) insects undergo metamorphosis.

    Neurobiologists from the University of Leicester have shown that insect limbs can move without muscles - a finding that may provide engineers with new ways to improve the control of robotic and prosthetic limbs

    not even gears are a human invention it seems ... Gears are found rarely in animals and have never been reported to intermesh and rotate functionally like mechanical gears. We now demonstrate functional gears in the ballistic jumping movements of the flightless planthopper insect Issus. The nymphs, but not adults, have a row of cuticular gear (cog) teeth around the curved medial surfaces of their two hindleg trochantera. The gear teeth on one trochanter engaged with and sequentially moved past those on the other trochanter during the preparatory cocking and the propulsive phases of jumping. Close registration between the gears ensured that both hindlegs moved at the same angular velocities to propel the body without yaw rotation. At the final molt to adulthood, this synchronization mechanism is jettisoned.

  • A new experiment reported in Physical Review Letters shows that—contrary to popular wisdom—paddling can be as effective in air as it is in water. This could imply that insects evolved their flight capability from some earlier swimming trait.
  • Using high-speed video cameras to track wing motion, the team observed certain cases where the flies paddled their wings forward and backward. To confirm that this was indeed drag-based motion, the team plugged their wing data into an “insect flight simulator” and found that they could reproduce the fly’s overall movement. The authors constructed a simple model of paddling, which seems to support the theory that insect wings evolved in water.

    Electron microscope studies reveal that the electron bombardment leads to polymerization of the outer layer of some insect larva's skin and protects them from dehydration. Artificial method to create this effect tested as well. Allows observation of living animals under electron microscope! Question: can the insects still breath after they are back in air? :-S

    The Robobee takes off without guide wires! It is still powered via a wire, and the control is done with the help of a VICON system and on an external computer, but this still is an amazing feat!

    The way they make this thing is just as impressive. The manufacturing technique is "pop-up book" folding, a method that has been developed by the same group and that allows a two dimensional monolithic MEMS structures to be easily assembled into a 3D structure. I actually put this as an item of the "Technology List 2020" on the wiki this morning.

    I agree, manufacturing is the amazing thing here ..... as soon as the power-consumption/density problem is solved these things will really take off :)

    Speed is blinding. Just ask the tiger beetle: This predatory insect has excellent sight, but when it chases prey, it runs so fast it can no longer see where it's going.

shared by pacome delva on 24 Aug 10 - Cached
  • Researchers thought that flies chose their altitude based on optic flow, a phenomenon familiar to anyone who has ridden an airplane.
  • The team's observations, published online today in Current Biology, suggest that flies base their cruising altitude on horizontal edges and landmarks—such as table surfaces or tree tops—and not on how fast the ground is moving beneath them. The edge-tracking strategy may enable flies to keep tabs on possible landing spots.
  • This may be the general principle" for all flying insects, he says.

phy swarms

shared by pacome delva on 28 Jul 10 - Cached
  • Swarms of insects or schools of fish can suddenly switch direction, seemingly at random. A research team now believes they understand why. In the August Physical Review E they describe experiments with locusts and their mathematical model of the swarm. The model suggests that tiny alignment errors between neighboring individual locusts within the swarm, which normally cancel each other, can accumulate over long times and eventually cause the entire swarm to suddenly move in a new direction.

  • Insects can execute flying feats more impressive than fighter jets, and a team of researchers has now learned the trick behind one of them. They used high speed video cameras and a new 3D reconstruction technique to show how fruit flies execute their acrobatic turns. As they report in the 9 April Physical Review Letters, despite the complex wing motions, a fly can execute quick pirouettes by adjusting just a single parameter that controls the difference between the way its left and right wings oscillate. The results may be relevant for engineers designing flight control strategies for tiny robotic insects for search-and-rescue and surveillance.

    We show here that the mosquito cannot only give rise to a higher water-supporting force than the water strider if the ratio of the water-supporting force to the body weight of the insect itself is compared, but also can safely take off or land on the wate
