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,
Ant colony. This allows other ants to detect what task group (e.g., foraging or nest maintenance) other colony members belong to. In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to raise new queens in the colony. Some ants produce sounds by stridulation, using the gaster segments and their mandibles. Sounds may be used to communicate with colony members or with other species. Ants attack and defend themselves by biting and, in many species, by stinging, often injecting or spraying chemicals, such as formic acid in the case of formicine ants, alkaloids and
