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
Meat ant of active mounds declined, but this effect was only temporary. This is due to colonies only having of bait which was insufficient to eliminate further nests, but the effect may have been more dramatic if extra bait was used. Meat ant The meat ant ("Iridomyrmex purpureus"), also known as the gravel ant or southern meat ant, is a species of ant endemic to Australia. A member of the genus "Iridomyrmex" in the subfamily Dolichoderinae, it was described by British entomologist Frederick Smith in 1858. The meat ant is associated with many common names due to its appearance, nest-building behaviour and
