Ant new estimates suggest that nearly 9% of all plant species may have such ant associations. Some plants in fire-prone grassland systems are particularly dependent on ants for their survival and dispersal as the seeds are transported to safety below the ground. Many ant-dispersed seeds have special external structures, elaiosomes, that are sought after by ants as food. A convergence, possibly a form of mimicry, is seen in the eggs of stick insects. They have an edible elaiosome-like structure and are taken into the ant nest where the young hatch. Most ants are predatory and some prey on and obtain food
Ant mimicry call of ants so they can integrate themselves into the nest. In "A. dentatis" the tubercles release the mimicking pheromone which elicits "A. caprensis" to care for the mimics as they would their own brood. In these relationships worker ants give the same preference to the Lycaenid's as they do to their own brood, demonstrating that chemical signals produced by the mimic are indistinguishable to the ant. This process is also used by larvae of the European Lycaenid species "Phengaris rebeli" which live in the nests of "Myrmica" ants and feed on their ant brood. Wasmannian mimicry occurs when two
