Sunday Night Movie: Trophallaxis

And now, a short video I made a few years ago:

Ants exchange food with each other far more frequently than nutrition requires. Liquid food-sharing, called trophallaxis, instead serves a communicative function, helping spread information among a colony’s workers. This video documents the behavior in a colony of captive Camponotus pennsylvanicus kept in a lab at the University of Illinois.
