![]() gracilipes commonly found a colony independently may be its native localities. In ants, independent colony foundation is an ancestral trait for species with alate queens, and so it is thought that the areas where A. ![]() Solitary founding queens or founding colonies with nanitic workers as produced in the laboratory have never been found for this species in research on ants for the last 25 years at several places in Southeast Asia. After 40 days, the workers reared claustrally by the queens were nanitic, having a head width significantly smaller than those of a mature colony. These nests were put in an incubator with constant temperature (26☌) and were not provided any prey or water for keeping the condition of claustral colony foundation. The queens were kept individually in artificial nests. It has been considered that these carbohydrate-rich resources promote ant invasions by providing high-energy fuel for greater activity, growth and the establishment of dominant supercolonies, as well as drive the aggressive behaviors of some invading ant species.Īnoplolepis will generally only demonstrate aggression towards other ants when defending resources, other than that, they normally only display evasive or indifferent behaviour when individuals or groups are confronted. gracilipes obtains carbohydrates and amino acids from plant nectaries and especially from honeydew excreted by Homoptera, which it tends on stems and leaves of a wide variety of tree and shrub species.Ī factor that may promote the success of invasive ants is their ability to exploit these carbohydrate resources. ![]() ![]() In addition to these protein-rich foods, A. Just like Oecophylla and BCA, YCA workers subdue their prey down by a method known as spread-eagle, where workers pull the prey’s appendages in different directions, while spraying them with formic acid. ![]()
