Oecophylla smaragdina (featured), Oecophylla sp.
Found in Australia and South East Asia, particularly Philippines.
Their nests are found in forest trees.
They farm scale bugs for their honeydew, and eat small insects.
Established colonies can reach up to half a million individuals.
Weaver ants are best known for their remarkable nest construction. Using precise coordination, the weaver ants create very strong ant chains by linking legs to pull and bend leaves into desired tent like positions. The ants then use their own larvae to secrete a silk that is used to stitch leaves together to create a nest. They may have several nests dominating a few trees at once.
They are very aggressive territorial ants and for over 1000 years they have often been used by farmers to control agricultural pests.
Oecophylla smaragdina workers have a vice like grip and tremendous strength. A worker has been recorded to support 100 times its own weight whilst standing upside down on glass, see ant facts no 2.
20-25mm, a strong ant, normally green and brown, monogyn (one queen per colony).
Risk level 3
Strong mandibles allow for a painful slicing bite, they spray formic acid into any wounds. A very aggressive ant.
