ATTA LAEVIGATA Meaning and
Definition
-
Atta laevigata, also known as the leafcutter ant, is a species of ant belonging to the tribe Attini, commonly found in tropical rainforests of Central and South America. These ants are renowned for their unique behavior of cutting and harvesting leaves to cultivate a specific fungus, which serves as their primary food source. With a size ranging from 10 to 14 mm, Atta laevigata is characterized by its robust body structure, elongated head, and strong mandibles.
The workers of Atta laevigata are divided into different castes, namely minor, medium, and major, each having different roles within the colony. Minors are responsible for collecting vegetation from nearby trees and carrying it back to the nest, while mediums work as intermediaries, transporting and processing the harvested leaves. Majors, on the other hand, perform the tasks requiring strength and defense, such as protecting the colony and enlarging underground chambers.
The mutualistic relationship between Atta laevigata and the cultivated fungus is the key to their survival. The ants use small fragments of leaves to feed and cultivate the fungus within specific chambers in their nests. In return, the fungus provides the ants with a rich source of nutrients, including carbohydrates and proteins.
However, leafcutter ants are also considered agricultural pests since they can have a detrimental impact on crops and plants when their foraging activities target cultivated vegetation. Therefore, managing their populations becomes crucial in agricultural regions where Atta laevigata is prevalent.
Etymology of ATTA LAEVIGATA
The word "atta laevigata" appears to be a scientific Latin binomial, commonly used in the field of entomology. It is used to refer to a species of leafcutter ant belonging to the genus Atta.
