Answer» 1. Introduction Butterflies are one of the most conspicuous species of Earth’s biodiversity. Being extremely responsive to any changes in their environment, namely, temperature, humidity, light, and rainfall patterns [1–4], these insects are identified as useful bioindicators. They have different requirements for different habitat types for mating, breeding, and nectaring and are, thus, in sync with the diversity and quality of their habitats. The present STUDY aims to examine the diversity and distribution of butterflies across three different habitats, namely, dry deciduous, open scrub, and urbanized habitat. A checklist of butterfly species is also provided. 2. Study Area The study was done in Indian Institute of Forest Management, Bhopal (23.208371°N and 77.384417°E), from July 2012 to March 2013. The location of campus, built on a hill at an elevation of about 556 m and surrounded by water on three sides, along with the wide range of climatic conditions that it passes through brings in DIVERSE structure of habitats. The major types of vegetation included grasslands, open scrub forest, and dry deciduous forest and bamboo groves. The study was conducted in 12 transects (each approximately 300 to 500 m long) covering an area of 93-hectare campus. For our study, transects were divided into three habitats according to general landscape attributes and vegetation present there. The chief habitat types were as follows: (1) open scrub, (2) dry deciduous, and (3) urbanized habitat .Results A total of 55 butterfly species with a total of 815 individuals belonging to 5 families were recorded (with photographic record) during the study. The butterfly list along with their abundance in different habitats is given in Table 1. There are 8 species with lowest individual number having abundance less than 5 in all the three habitats. The three most abundant species are Eurema brigitta (with 48 individuals) followed by Eurema hecabe (with 45 individuals) and Junonia lemonias (with 34 individuals). The greatest number of all these three species occurred in open scrub. Out of 55 species, 52 were found in open scrub followed by 49 species in dry deciduous habitat and then 44 species in urbanized habitat. A total of 815 individuals were recorded from the campus with highest abundance in open scrub () followed by dry deciduous habitat () and urbanized habitat (). Out of the five families of butterflies, Nymphalidae were the most commonly recorded, ACCOUNTING for 38% () of total species recorded followed by Lycaenidae 23% (), Pieridae 10% (), and Hesperiidae 12% () of total species and minimum was recorded for Papilionidae 7% (). |
