Weaver ants live in trees and are known for their unique nest building behavior where workers construct nests by weaving together leaves using larval silk. Colonies can be extremely large consisting of more than a hundred nests spanning numerous trees and containing more than half a million workers. Like many other ant species, weaver ants prey on small insects and supplement their diet with carbohydrate-rich honeydew excreted by small insects. Weaver ants vary in color from reddish to yellowish brown dependent on the species. When these nasty reddish ants bite, they squirt formic acid that is secreted from their abdomen into the wound, making it doubly painful. They do not have a stinger, If the nest is disturbed, for example you have taken a stick and poked the nest, the thousands of ants residing inside will give a noisy warning by tapping on the leaves from within.
