Michael Dickinson Quotes
-
The genus Drosophila is one of the great success stories. There's hundreds of species within the genus. They're on every continent except Antarctica, they're in tropical rain forests, they're in deserts, they've evolved many exotic mating behaviors, and they're capable of incredibly long-distance flights.

For many years in my laboratory and other laboratories around the world, we've been studying fly behaviors in little flight simulators. You can tether a fly to a little stick. You can measure the aerodynamic forces it's creating. You can let the fly play a little video game by letting it fly around in a visual display.

If flies are a great model, they're a great model for flies. These animals, you know, they're not like us. We don't fly. We don't have a compound eye. I don't think we process sensory information the same way. The muscles that they use are just incredibly much more sophisticated and interesting than the muscles we use.

Like many insects, flies are most sensitive to green light. This means that they would see their world as 'black and white,' in that they can't see the multiple colors required to reconstruct a color image of the world. They do, however, have specialized cells that enable them to see ultraviolet wavelengths.
-
Only flies have true halteres. In fact, the scientific term for flies, 'diptera,' means 'two wings.' Most insects, including bees, have two pairs of wings for a total of four. In flies, the hindwing pairs have been transformed through evolution into the halteres.
-
If you watch a fly on, say, a coffee table, you'll see that they're rubbing their little legs together to groom themselves; they're actually quite clean creatures.
-
I grew up watching 'Star Trek.' I love 'Star Trek.' 'Star Trek' made me want to see alien creatures, creatures from a far-distant world. But basically, I figured out that I could find those alien creatures right on Earth. And what I do is I study insects.
-
I'm obsessed with insects, particularly insect flight. I think the evolution of insect flight is perhaps one of the most important events in the history of life. Without insects, there'd be no flowering plants. Without flowering plants, there would be no clever, fruit-eating primates giving TED Talks.

Fly flight is just a great phenomenon to study. It has everything - from the most sophisticated sensory biology; really, really interesting physics; really interesting muscle physiology; really interesting neural computations.

Although their maneuverability is limited, blind flies can fly remarkably well.
