Three males above one female.


Model for position control 

The excellent following behaviour of  Eristalis nemorum males is suggesting an innate fast and accurate servo control system. The complete system is very complex, including eyes, neurons in different layers and the motor control of the wings. However a largely simplified model may be of use to gain more insight and to be able to relate the experiments.
