Subspecies
Synonyms

Aggressive arboreal ants that use larval silk to weave together leaves to form their nesting cavities. A mature colony of Oecophylla longinoda can entirely dominate a tree (sometimes several) with nests distributed throughout their heavily defended arboreal territory.

Biology

There is a webpage with a list of some recent publications about Weaver Ants. You can also read an overview of their biology from the a chapter in The Ants: The Weaver Ants (Hölldobler and Wilson 1990).

Nene et al. 2015 (abstract): Mating in most species of ants occur during nuptial flights. In the African weaver ant, Oecophylla longinoda Latreille, mating has previously been hypothesized to take place within the nest before the nuptial flight but no research data has ever been presented to support this. Understanding the mating strategy of O. longinoda is important for its successful application in biological control programs. Here we report on the findings from studies conducted in Tanzania to determine whether mating occur prior to dispersal flight. Winged O. longinoda queens collected at four steps; before taking flight, immediately after leaving the nest, up to 12h after leaving the nest and after settling naturally following the dispersal flights were examined. Mating in captivity with varied number of males and queens was also assessed. Results showed that no eggs hatched from any of the 527 winged queens that were collected prior to their dispersal flights and no mating attempts in captivity lead to viable offspring. Only eggs produced by queens collected after settling naturally (N=65) hatched into larvae. High percentages (88.73) of eggs that hatched were laid by queens that shed wings and laid their eggs within 3 days after nuptial flights. Findings from the current study suggest that mating of O. longinoda queens take place during a nuptial flight and does not take place within the nest, as previously suggested. Time from nuptial flights to shedding of wings and egg laying translates to hatchability of the eggs.
