Experimentally staged conflicts between 'chilled' workers of Iridomyrmex purpureus from different nests revealed that individuals reacted more aggressively towards intruders from nests further away than from neighbouring nests. Further bioassays using filter paper coated with extracted cuticular hydrocarbons revealed a similar pattern. These experiments (conducted blind) demonstrated that recognition between conspecific non-nestmates is mediated by these chemicals.
