VARGAS- ZAPATA, María Angélica et al. Plant Composition, Feeding Preferences and Abundance of Biblidinae (Lepidoptera: Nymphalidae) in a Tropical Dry Forest Fragment in the Department of Atlántico, Colombia. Acta biol.Colomb. [online]. 2015, vol.20, n.3, pp.79-92. ISSN 0120-548X.  https://doi.org/10.15446/Abc.V20n3.42545.

The abundance and spatio-temporal variation of butterflies of the Biblidinae subfamily (Lepidoptera: Nymphalidae) in a fragment of Tropical dry forest at the Reserva Campesina La Montaña (RCM), Atlántico, Colombia; from January until August 2011, was analyzed. Within the study area four points were marked; Van Someren-Rydon traps were placed.in each point using rotten squid, fermented fruit and a mixture of both as bait. In addition, a characterization of the vegetation by point was performed, taking data of the diameter to the breast height (DBH), height and size of treetop of all woody plants with a DBH greater than or equal to 2.5 cm. In total 76 butterfly individuals grouped in six species and four genera were captured; being Hamadryas februa (Hübner) the most dominant with 32 individuals. The greatest richness and abundance was recorded in March (6 species and 25 individuals), during the first rains in the study area. The point 3 presented the highest values of diversity and abundance (five species and 37 individuals) of Biblidinae and the higher density of trees (D= 0,28 individuals/m2). The structure of this butterflies group presents a spatio-temporal pattern in this reserve. The principal components analysis showed that the total basal area (ABT) and the density (D) of woody plants, can be considered a determining factor in the distribution and abundance of species of the subfamily Biblidinae at the RCM.
