abstract="In French Guiana, the arboreal nests of the swarm-founding social wasp Protopolybia emortualis (Polistinae) are generally found near those of the arboreal dolichoderine ant Dolichoderus bidens. These wasp nests are typically protected by an envelope, which in turn is covered by an additional carton {\textquoteleft}shelter{\textquoteright} with structure resembling the D.~bidens nests. A few wasps constantly guard their nest to keep D.~bidens workers from approaching. When alarmed by a strong disturbance, the ants invade the host tree foliage whereas the wasps retreat into their nest. Notably, there is no chemical convergence in the cuticular profiles of the wasps and ants sharing a tree. The aggressiveness of D.~bidens likely protects the wasps from army ant raids, but the ants do not benefit from the presence of the wasps; therefore, this relationship corresponds to a kind of commensalism. R{\'e}sum{\'e} En Guyane fran{\c{c}}aise, les nids de la gu{\^e}pe Protopolybia emortualis (Polistinae) se trouvent g{\'e}n{\'e}ralement {\`a} proximit{\'e} de ceux de la fourmi arboricole Dolichoderus bidens (Dolichoderinae). Ces nids de gu{\^e}pes sont typiquement prot{\'e}g{\'e}s par une enveloppe de carton, elle-m{\^e}me recouverte d{\textquoteright}une autre enveloppe formant un abri qui ressemble aux nids de carton de D.~bidens. Quelques gu{\^e}pes gardent leur nid en permanence afin de tenir {\`a} distance les ouvri{\`e}res D.~bidens. Alarm{\'e}es par une forte perturbation, les fourmis envahissent tout le feuillage de leur arbre support alors que les gu{\^e}pes se r{\'e}fugient dans leur nid. Il n{\textquoteright}y a pas de convergence chimique entre les profils cuticulaires des gu{\^e}pes et ceux des fourmis associ{\'e}es. Il est tr{\`e}s probable que les P.~emortualis b{\'e}n{\'e}ficient d{\textquoteright}une protection contre les fourmis l{\'e}gionnaires gr{\^a}ce {\`a} l{\textquoteright}agressivit{\'e} des D.~bidens, mais il n{\textquoteright}y a pas r{\'e}ciprocit{\'e}, de sorte que cette relation correspond {\`a} une forme de commensalisme.",
