A Myrmica rubra worker deposits the attractant secretion of its Dufour's gland when walking around an ant of another species (e.g. Lasius flavus). If the Lasius is not killed, the worker walks to the nest, laying a trail of the secretion of its poison gland's secretion (Fig. 2). The worker reaches the nest, meets members of the society and walks back to the Lasius, depositing a trail of the attractive secretion of its Dufour's gland (Fig. 3). The trail attracts many ants to the place where help is needed. © 1974 Springer-Verlag.
