trophallaxis

Worker termites feed other castes digested food in a process called trophallaxis.

The researchers trained the computer to identify a behavior called trophallaxis, in which honey bees feed their fellow workers by regurgitating food from a pouch called a crop.

About half as much trophallaxis took place with sick bees compared with normal workers.

Wheeler proposed that “trophallaxis” – a word he invented for the way insects regurgitate and share food among themselves – was the secret sauce, the superglue of societies both insect and human, and the foundation of economics.

Simone Leigh’s fantastic “trophallaxis,” a hanging bundle of nut-shaped, slate gray terra-cotta breasts, bristling with fully extended car antennas, may be an exception.
