  		Fig. 1. The aggressive response of L. humile to conspecific surface lipids supplemented with n-alkane hydrocarbon standards. L. humile responded aggressively to changes in the relative abundance of n-alkane hydrocarbons in their cuticular hydrocarbon profile. The ants did not respond more aggressively to n-alkanes when presented alone than to the blank control or nestmate surface lipids. Values are means ± s.e.m. (N=8). The line above the bars indicates that LSD post-hoc analysis showed no statistical difference among the treatments.

  		Fig. 2. The aggressive response of L. humile towards heterospecific hydrocarbons, structural classes and controls. (A) Argentine ant response to Formica moki hydrocarbons, individual hydrocarbon structural classes, mixtures of hydrocarbon classes, hydrocarbons extracted from F. moki, and controls. (B) Argentine ant response to mixtures of synthetic hydrocarbon standards and controls. Values are means ± s.e.m. (N=8). The line above the bars indicates that LSD post-hoc analysis showed no statistical difference among the treatments.

  		Fig. 3. The aggressive response of Aphaenogaster cockerelli towards heterospecific hydrocarbons from Pogonmyrmex barbatus, individual hydrocarbon structural classes, and mixtures of hydrocarbon classes. Values are means ± s.e.m. (N=10). The line above the bars indicates that LSD post-hoc analysis showed no statistical difference among the treatments.
