Meat ant of the colony may deteriorate from overshadowing. Members of an affected meat ant colony later move to a nearby satellite nest that is placed in a suitable area, while invading banded sugar ants fill nest galleries up with a black resinous material. Meat ants sometimes attract cats because of the chemicals they secrete (dihydronepetalactone, isodihydronepetalactone and iridomyrmecin). Meat ants are generally intolerant of myrmecophiles (which are insects or other organisms that share positive interspecies associations with ants) living in their colonies, but "Cyclotorna" larvae are known to dwell in colonies. Although "Sphallomorpha" larvae sometimes prey on workers as discussed earlier,
Pharaoh ant been introduced. It also helps prevent ants from concentrating on an undesirable trail. Thus, the repellant pheromone makes the pharaoh ant a particularly efficient forager. Despite their extreme importance, there is an adaptive value to using pheromones sparingly, as it streamlines communication during important decision-making situations, such as a nest migration. Pharaoh ants use a positive feedback system of foraging. Each morning, scouts will search for food. When one finds it, it will instantly return to the nest. This causes several ants to follow the successful scout’s trail back to the food source. Soon, a large group will be upon
