Ants secrete and recognize specific blends of hydrocarbons in the cuticle, which enables them to display aggressive behavior toward non-nestmates. This identification process is thought to occur at a higher neural level. Ozaki et al. have found chemosensory sensilla in the ant antenna that respond to cuticle hydrocarbon blends from non-nestmates and have identified a protein that may carry the compounds to sensory receptors in the sensilla. This finding suggests that chemical information is also processed peripherally.
