Nesting Habits

Verza et al. (2019): Seven nests of Acromyrmex landolti were excavated in a semiarid region of the Caatinga, an exclusively Brazilian biome. The nests were measured both externally and internally and then photographed. Nests were found in open and sunny areas and externally all nests presented a loose soil mound, straw protection over the entrance hole, and a refuse dump. The number of underground chambers found ranged from 4 to 17, with differing heights, widths, and lengths. The chambers were found from near the surface of the ground to a maximum depth of 1.70 m. Our results showed that strategies used by A. landolti include the construction of an ornate straw tower at the entrance of the nest and the construction of deep underground rooms, with the chambers of fungi near the water table. The structure of the nests of A. landolti is probably related to its habit of building their nests in open, sunny locations associated with environmental factors characteristic of the semiarid climate of the Caatinga biome.
