  abstract = {{I}n the {N}eotropics where it was introduced, the invasive ant {P}heidole megacephala counterattacked raids by the army ants {E}citon burchellii or {E}. hamatum. {T}he {E}citon workers that returned to their bivouac were attacked and spread-eagled and most of them killed by their outgoing colony mates. {L}ittle by little the zone where returning and outgoing {E}citon workers encountered one another moved away from the {P}heidole nest which was no longer attacked, so that most of the colony was spared. {U}sing a water-based technique rounded out by bioassays, we show that {P}heidole compounds were transferred onto the {E}citon cuticle during the counterattacks, so that outgoing workers do not recognize returning colony mates, likely perceived as potential prey. {B}ecause {P}. megacephala is an introduced {A}frican species, this kind of protection, which cannot be the result of coevolutive processes, corresponds to a kind of by-product due to its aggressiveness during colony defence.},
