About the Asian Weaver Ant
Oecophylla smaragdina (common names include Asian weaver ant, weaver ant, green ant, green tree ant, and orange gaster) is a species of arboreal ant found in tropical Asia and Australia. These ants form colonies with multiple nests in trees, each nest being made of leaves stitched together using the silk produced by the ant larvae, hence the specific name oecophylla (Greek for "leaf-house").
Workers and major workers are mostly coloured orange. Workers are 5–7 mm (0.20–0.28 in) long; they look after larvae and farm scale bugs for honeydew. Major workers are 8–10 mm (0.3–0.4 in) long, with long, strong legs and large mandibles. They forage, assemble, and expand the nest. Queens are typically 20–25 mm (0.8–1.0 in) long, and normally greenish-brown, giving the species its specific name smaragdina (Latin: emerald).
Oecophylla smaragdina has a widespread distribution in tropical Asia and Australia, with its range extending from India through Indonesia and the Philippines to Northern Territory and Queensland in Australia. It is an arboreal species, making its nests among the foliage of trees. Nests are constructed during the night, with major... Wikipedia →
