About the Chicatana Leafcutter Ant
Atta mexicana is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Atta. This species is from one of the two genera of advanced attines (fungus-growing ants) within the tribe Attini.

The ants cut leaves and grow a basidiomycete fungus called Leucoagaricus gongylophorus (Agaricaceae) with them. Oleic acid is one of their undertaking triggers.
A. mexicana is found in Mexico (where it is commonly called hormiga chicatana, hormiga podadora de hoja/desert ant and mochomo), and crosses into Arizona, United States. This species is highly adaptive, and thrives in such urban areas as Puerto Vallarta. Densities of A. mexicana nests are very high in numerous areas, including the resort community of Nuevo Vallarta.
The species is found in various locations of central and southern Mexico during the start of the rainy season, when the soil becomes wet and the ants leave for their nuptial flight. That time of the year is... Wikipedia →
