The genus Oecophylla is known for the species commonly referred to as weaver ants. These ants are remarkable for their unique nest-building behavior, where they use their larvae to produce silk to weave leaves together, creating large, complex nests in trees. Oecophylla ants are typically reddish, green or orange in color and are medium to large in size. They are highly territorial and known for their aggressive behavior in defending their nests. Oecophylla species are also known for their cooperative foraging and strong social organization, often forming large colonies that can dominate significant areas in tropical and subtropical regions.
