Trophallaxis

Formicine : Camponotus sp

Spanish:
Las hormigas que han recogido un poco de néctar pueden llevar más que ellas necesitan para sí mismos en sus cosechas y este suplemento se puede compartir con otros miembros de la colonia cuando consiguen de nuevo a la jerarquía. Esto que comparte se hace cuando una hormiga pasa una gota del líquido de su cosecha en su boca y una segunda hormiga la recoge en su boca que esto se llama los "trophallaxis" y mira a nosotros como dos hormigas que se besan, él es tan importante para las hormigas como el besarse está a nosotros, si no más tan.

English:
Trophallaxis is the transfer of food or other fluids among members of a community through mouth-to-mouth (stomodeal) or anus-to-mouth (proctodeal) feeding. It is most highly developed in social insects such as ants, termites and bees. The word was introduced by the entomologist William Morton Wheeler in 1918. The behaviour was used in the past to support theories on the origin of sociality in insects.
In ants, individual colony members store food in their crops and regularly exchange it with other colony members and larvae to form a sort of "communal stomach" for the colony. In many termites, proctodeal trophallaxis is crucial for replacing the gut endosymbionts that is lost after every molt. This should not be confused with coprophagia. Some vertebrates such as birds also feed their young through trophallaxis.
Trophallaxis is also performed by members of the dog family. In the wild, a hunting dog will regurgitate food gorged while far from its lair in order to feed its puppies. These puppies lick the face of the adult in order to trigger trophallaxis. Domestic dogs are tame because of arrested development of their wild tendencies and will treat certain humans, in particular their owner, as lifelong 'parents'. Therefore, when a dog licks your face, it may be that he's manifesting a vestigial feeding instinct.
Trophallaxis serves as a means of communication, at least in bees and ants. In some species of ants, it may play a role in spreading the colony odour that identifies members

French:
Communication par trophallaxie: attouchement mutuel des antennes, léchages routiniers de la reine, des oeufs, des larves, des ouvrières entre elles.
La trophallaxie est un mode de transfert de nourriture, utilisé par certains insectes.
Les fourmis ouvrières possèdent deux estomacs. Lorsque l'une d'elles ingurgite de la nourriture, la majeure partie de celle-ci est stockée dans le second estomac, le jabot social, appelé également estomac social.
La trophallaxie consiste en une régurgitation de la nourriture pré-digérée contenue dans ce dernier afin de nourrir d'autres fourmis. Ce transfert ne concerne pas exclusivement les aliments mais permet également de faire circuler des informations dans la colonie via des messages chimiques (phéromones).
La trophallaxie existe aussi chez l'abeille et la plupart des insectes sociaux.
