To try to defend the colony from this incessant predation, the bees fight back by forming a cluster on the flight board. They thus save a few foraging bees returning after gathering nectar and pollen from the flowers. France

Apidologie - Bees in a flight tunnel. This procedure was used to show that the evaluation of distance by bees proceeds from their visual system. And through the white and black stripes, its has been shown that it also depends on the landscape's structure. This experiment was carried out by then calculating the length of the bees's dance in relation to the food source of which the distance was identified. /

Apidologie - A bee in front of an odor gun. This technique allows for an association between an odor and a sugary reward. A sweet solution is applied to the antennas and the bee stretches out its proboscis, its little trunk. This odor-reflex association has brought to light the bees' capacity to remember odors and the time necessary to acquire olfactory memory. But also more complex learning: for example, an odor A is associated with a sugary solution and an odor B is not. Then, shortly after, it is reversed: the odor A is no longer associated with sugar but the odor B is. Result: the bee is capable of replacing the first signal by the new one.

Honey bee (Apis mellifera) - Microchips are used by researchers to mark the bees and identify them with a scanner at the entrance to the hive or near the nurse bees. In that way, it is possible to monitor the bees' activities on an individual level. The times they go out, etc… Research Center HOBOS, Würzburg, Germany.
