The distribution of biological diversity is one of the major questions for science. Several theories were proposed in attempt to understand the patterns and process that regulate the richness of extant species: species-energy theory, metabolic theory of ecology, habitat heterogeneity, and tropics as museum, cradle or casino. Terrestrial ecorregions are land units that contain similar biotic and abiotic factors, what makes them more alluring and efficient for conservation planning and land use than using geopolitical divisions, still used by several conservation institutions and governments. Odonata is one of the oldest orders of insect, belonging to the clade Paleoptera. Those insects, for being thightly related to environmental conditions and vegetation structure, are widely utilized as bioindicators and in studies of spatial patterns. In this thesis, we evaluated the lack of knowledge around Odonata geographic distribution in the Neotropical region and the way that its species composition is affected by both climate and space.
