Keanekaragaman Kupu – kupu (Rhopalocera) di Taman Flora Surabaya

Abstract

Taman Flora is one of the city parks in Surabaya City parks have an important role for the urban ecosystem. City parks are needed for interaction space between humans and the environment as well as a living space for flora and fauna, especially butterflies. Research on butterfly diversity is very important because the related data is still not comprehensive from various regions of Indonesia. This study aims to determine the level of diversity of butterflies as well as abiotic conditions in Taman Kota Surabaya. The data collection method combines the transect method and the VES (Visual Encounter Survey) method by tracing existing roads as well as counting and recording the number of species and individuals encountered. Butterflies that were found in the study were 12 species from 3 different families with a total of 178 individuals. The results of the butterfly diversity index were (H’) = 2.33, evenness (E) = 0.94, dominance (C) = 0.11. The abiotic factors at Taman Flora were classified as optimal, the temperature 29,6-30,9 °C the humidity 71-84% and light intensity 18342-22976 lux  so that the environmental conditions at that location were good for the survival of the butterflies. The most commonly found species is Eurema hecabe and Leptosia nina.
