One-strided waggle dance in bees

Article Abstract:

The waggle dance performed by honeybees, indicating food sources to their nestmates, comprises of a single stride during which the bee moves forward and the feet remain in contact with the comb. The distance of the food source has no effect on the contact of feet with the comb. However, the speed of the forward motion is faster for near sources. The contact with the comb is probably a communication method as it enhances the transfer of vibrations to the comb. The feet make small uncoordinated movements during the waggle dance and coordinated movements during normal walk.

Flies go with the flow

Article Abstract:

Flies control their flight by monitoring the apparent motion of their surroundings as they fly. The movements of yaw, pitch and roll are interpreted in terms of patterns of image motion, or flow fields by a fly's nervous system. The flow fields are detected by the VS neurons in the lobula plate region of a fly's brain. All neurons are specifically tuned to responding to either the motions of yaw, pitch or roll. Neuron H(sub x) responds most strongly to movement in the forward direction. These visual processing findings may be applicable to navigation of mobile robots.
