Abstract
RIVERA-GALLEGO, Iván-Darío and PINZON-FLORIAN, Olga-Patricia. Fruit-feeding butterflies (Lepidoptera: Nymphalidae) in eucalyptus plantations and gallery forests in the Colombian Orinoquia. Rev. biol. trop [online]. 2022, vol.70, n.1, pp.768-786. ISSN 0034-7744. http://dx.doi.org/10.15517/rev.biol.trop..v70i1.50860.
Introduction:
An economic activity that has boomed in the last decade in Colombian highlands is the afforestation of anthropized savannas, but its role in the conservation of fruit-feeding butterflies of gallery forests within forest cores is unknown.
Objective:
To compare the diversity of fruit-feeding butterflies in eucalyptus plantations and gallery forests, and the role of environmental variables.
Methods:
We used Van Someren-Rydon traps, two replicates of four traps, on each of four habitats sampled simultaneously from December 2020 to July 2021: four-years-old eucalyptus plantation; six-years-old eucalyptus plantation; dry soil gallery forest and waterlogged gallery forest. We also recorded ten abiotic, structural, food and habitat variables.
Results:
We collected 227 specimens of fruit-feeding butterflies (30 species, 23 genera, and 5 subfamilies within the family Nymphalidae). There were more species in the forests. The butterfly species varied over 50 % between the habitats; Satyrinae were more diverse in plantations.
Conclusion:
Afforestation in this area provides habitats for some species of fruit-feeding butterflies from adjacent natural forest remnants. Afforestations represent an intermediate disturbance scenario between the two dominant landscape units in the region.
