Study of Butterfly Diversity (Subordo Rhopalocera) Based on Altitude in the Pranji Hill Kebumen Area

Abstract

This study aimed to determine the composition of butterfly species and analyze the diversity index, uniformity index, and dominance index of butterflies found based on height in the Pranji Hill area. The research method used is exploratory descriptive research using the VES (Visual Encounter Survey) method. The observation transect used is point transect with a transect length of 800 meters. In this study, sampling points are divided into 3 stations (I, II, and III), each station size is made 200 x 50 meters with altitude variations of 300 meters above sea level, 400 meters above sea level, and 500 meters above sea level. The identification method used is Merfometric,
where researchers make identification by observing the morphological structure in shape, size, color and pattern which is then compared with the butterfly identification key. Data analysistechniques using diversity index data analysis (H'), uniformity index analysis (E), and dominance index analysis (C). The results of the study are the types of butterflies found in the Pranji Hill area on the basis height totaling 25 species from 4 families, namely 14 species from the famuly Nymphalidae 5 species from the family Pieridae, 4 species from the family Papilionidae, and 2 species from the family Lycaenidae. Based on the criteria for assessing the weighting of the environmental quality the diversity index value (H'), is moderate, the uniformity index value (E)
is high, and the dominance index value (C) is low.
