Oh, never mind:
"While many types of animals can learn behaviors by imitating other animals, ants may be the only group of animals besides primates and some other mammals in which interactive teaching behavior has been observed. Knowledgeable forager ants of the species Temnothorax albipennis directly lead naive nestmates to newly discovered food sources by the excruciatingly slow (and time-costly) process of "tandem running". The follower thereby obtains knowledge that it would not have, had it not been tutored, and this is at the expense of its nestmate teacher. Both leader and follower are acutely sensitive to the progress of their partner. For example, the leader slows down when the follower lags too far behind, and speeds up when the follower gets too close, while the follower does the opposite (Franks and Richardson, 2006)." -- from Wikipedia
