Dass mit dem Tandem ist wohl eine Methode Arbeiterinnen zum Futter zu tragen. Ich hab eine Veröffentlichung über Aphaenogaster gefunden:
Hyperlinks sind nur für registrierte Nutzer sichtbar"Worker recruitment is the behavioral sequence that allows a worker,
the recruiter, to bring a given number of nestmates, the
recruits, to a food source. Recruitment strategies can be
classified into three main categories (Wilson 1971) of
which tandem recruitment or tandem running is considered
least efficient because it allows the recruitment of only one
worker; during tandem running, the recruit follows the
recruiter in close antennal contact. Mass recruitment is the
most efficient strategy by which recruiters returning from a
food source to the nest lay a chemical trail that guides their
nestmates to the source."
