Oecophylla smaragdina - Green Tree Ants
Oecophyll are large arboreal ants of the African, Asian, and Australian tropics. These conspicuous insects are weaver ants, they create nests by pulling living tree leaves together and securing them with silk produced by the ants' larvae. Colonies can be large and territorial, covering several trees and containing dozens of nests.
