Abstract: The left and right antennae of stingless bees have different roles in learning and recall of olfactory memory. Antennal asymmetry in social behavior is reported here. Approaches and physical contacts were scored in dyads of stingless bees ('Tetragonula carbonaria'): dyads in which both bees had only their right antennae (left antennae removed) made significantly more physical contacts with each other than dyads in which both bees had only their left antennae. In dyads of one left and one right, it was found, unexpectedly, that the bee with a left antenna approached the bee with the right antenna more often that the other way around, and the bee with the left antenna often attacked (by biting) its hive mate. Hence, the low number of contacts in dyads of bees using their left antennae appears to be due to mutual avoidance. Whereas use of the right antenna stimulates positive contact, the left stimulates avoidance or attack. Via such left-right asymmetries, intact bees may compute behavior directed towards friend and foe. Such antennal asymmetry may have evolved concomitantly with eusocial behavior. We found no evidence that it was associated with significant differences in the number of olfactory or non-olfactory sensilla on the left versus right antenna.
