This research found that diversity and structure of Lepidoptera communities varies according to the habitats both in the piedmont plains and flood savanna of the Orinoco in Colombia. Sampled sites in the piedmont zone have greater similarity both in species richness and representativeness of some taxonomic groups, and there is also the presence of unique species such as Parides erithalion, Dismorphia crisia, Pereute leucodrosime and Pycina zamba. Moreover, sampled sites in the flood savanna zone are less diverse than the piedmont areas and more similar to each other, since they share a large percentage of the species composition, mainly Anartia amathea, Callicore cyllene, Chlosyne poecile and Siproeta stelenes, species that are adapted to disturbed habitats. Heraclides thoas, Adelpha alala, Danaus gilippus and Heliconius erato are categorized as common species because they are most often shared between sites and samplings. Finally, it highlights the dominance shown by subfamilies Biblidinae and Ithomiinae in most sites sampled in the plains piedmont. This result can be correlated to the high abundance and availability of resources over the different micro-habitats that make up these ecosystems, favoring the establishment of particular species.
