Male Cardiocondyla obscurior ants are diphenic (either winged or wingless). New research demonstrates that the dominant wingless (ergatoid) male is able to identify potential rivals before they emerge from their pupae. Constant patrolling of the nest ensures that this male is able to bite or chemically tag rivals as soon as they emerge from their pupae. Chemically tagged ants are quickly destroyed by workers.
Researchers have identified and synthesized the chemical cues by which Argentine ants distinguish colony-mates from rivals. By exploiting these chemicals, researchers have demonstrated that normally friendly Argentine ants can turn ... Read Post
Wingless males of the ant genus Cardiocondyla engage in fatal fighting for access to female sexual nestmates. Older, heavily sclerotised males are usually capable of eliminating all younger rivals, whose cuticle is still soft. It th... Read Post
