Thermographic recordings show that honeybees may receive nectar from foragers even during short trophallactic contacts

Forager bees that return from nectar sources transfer the gathered liquid to receiver hive mates through mouth-to-mouth contacts (trophallaxis). After returning from a nectar source, several trophallactic events of different lengths usually occur between the incoming forager and hive-mates. No unifi...

description Forager bees that return from nectar sources transfer the gathered liquid to receiver hive mates through mouth-to-mouth contacts (trophallaxis). After returning from a nectar source, several trophallactic events of different lengths usually occur between the incoming forager and hive-mates.
