Sanjay Sane, a biologist from the University of Washington and lead author of this week's Science article, "Antennal Mechanosensors Mediate Flight Control in Moths," collaborated with Case biologist Mark Willis, in studying the large moth Manduca sexta (tobacco hornworm moth) to unravel how it controls it flight in an effort to build a new generation of flying robots.

This information has the potential to help us design gyro-like stabilization capabilities for a small flying robot," said Willis.
While studying how moths use their antennae to sense smell, Willis noticed that when antennae were clipped or damaged, the moths struggled to maintain stable flight and would crash into walls, fly backwards or waver off course.If a severed antenna was reattached with Super Glue, the moth was able to regain flight control.
"This observation really emphasized to us that the antennae are more than just the moth's sense of smell," said Willis.
When placed under a microscope, a moth's antenna looks like a string of beads.
...
Fast flying insects need to know as soon as possible if they are veering of course to avoid crashing, according to Willis.

"Working with Sanjay, Alexandre and Tom is really fun," says Willis.
