During the Identidad Madidi expeditions between 2015 and 2017 across 15 sites, as well as additional efforts specifically focused on butterflies in 2018 and 2019, 1,564 butterfly species and subspecies were registered in the park including 876 new records for the park. This almost doubled the baseline for Madidi before the scientific expedition from 933 records to 1,809 species and subspecies. This total included 161 new species for Bolivia, and 3 are candidates as new species for science. The richest sites for butterfly diversity are the montane forests, piedmont forests and Amazonian forests and savannas. Madidi is now the protected area with the greatest confirmed butterfly species richness in the world. Its biogeographical characteristics have resulted in a high butterfly endemism.
