A team of 79 scientists from more than 50 institutions partnered to gather all available information regarding Mexican ants since 1894, the year in which the first geographical record of an ant is known for the country. In this new study, including more than 21,000 records, we showed that there are ~900 species of ants in Mexico, which are distributed unevenly across the country. Mexico is one of the relatively few countries along the interface of the tropical and temperate zones, and is a megadiverse country. These photographs illustrate the article “Mexico ants: incidence and abundance along the Nearctic‐Neotropical interface” by Wesley Dáttilo et al. published in Ecology. https://doi.org/10.1002/ecy.294
