For 20 years researching biomechanics wing flies, Michael Dickinson of the California Institute of Technology (Caltech) recently broke now. That was because he was always curious about the simple question, and frequently asked questions many people he encountered.

“Now I have the answer,” said Dickinson, who conducted the study with Esther M and Abe M Zarem. He discovered the secret after recording a number of maneuvers that threatened blow flies using a digital camera that can record speed and high resolution.

They found that flies can identify threats based on the location. His brain will calculate how far the threat against him before deciding to beat their wings and escape.

After predicting the direction of the threat, foot rests to fly in the opposite direction. All the preparation can be done away with very quickly, only 100 milliseconds after it detects a hazard. (more…)
