The Diversity of Butterfly in Air Dingin Landfills, Balai Gadang, Padang City

Abstract

The study of butterfly in the in Air Dingin Landfills needs to be carried out to find out what types of butterflies are in this area and how their diversity is, given the increasing area of Landfills that will change the surrounding environment into a place of rubbish heap. The study was conducted by implementing survey method with insect net. The collection of butterflies was carried out in 2 periods (2x6 = 12 days) in April-June 2019 during sunny weather from 09:00 – 12:00 of Western Indonesian Time. All butterflies were collected at ±5 m distance from the collector. The data was analysed to calculate abundance, relative abundance, frequency of the presence of butterfly, and determine diversity was conducted by using the Shannon-Wiener Index and Evenness index. The results obtained 5 families, 14 genera, 22 species, and 220 individuals consisting of 122 males and 98 females. The diversity index value obtained was 2.27 and categorised as the medium category it is mostly because, as assumed, the environmental conditions of the Air Dingin Landfills were still in good condition.

Butterfly Diversity from Isolated Lowland Area: An Assessment in Langsa Urban Forest, Langsa, Aceh, Indonesia

“…This situation is not surprising as Nymphalidae is the largest fam- ily with perhaps 650 species or 34.21% of all known butterflies (Widjaja 2014). On the other hand, the lowest number of species was recorded from the inconspicuous family of Hesperidae and is also similar to other areas in Indonesia, such as Baluran National Park (6.35%), Sangihe Island (0.64%), Talaud Island (3.12%) and Landsfill Balai Gadang (4.54%) (Leo et al 2016;Koneri & Nangoy 2019;Muhelni & Anwar 2020). Technical issues may also contribute to the low number of certain families.…”

Butterfly (Lepidoptera: Papilionoidae) diversity and structure community in Lumajang, East Java, Indonesia

“…Based on these findings, this study's results indicate that butterflies prefer habitats with optimal temperature and humidity, such as Community Forest. Furthermore, butterflies are poikilotherm organisms, so environmental temperature greatly influences their body temperature (Muhelni and Anwar 2020;Comay et al 2021). Temperature can also affect butterfly activity; for example, high temperatures can cause the volume of secretions in flowering plants to decrease, resulting in a lack of food intake (Ramesh et al 2012;Koneri et al 2022).…”
