Seasonal Variation in Diversity and Abundance of Butterfly at Sawanga Vithoba Lake Area District Amravati, Maharashtra India

Narendra Manwar and Varsha Wankhade
Butterflies are the best taxonomically studied groups of insects and are also good indicators of environmental changes. Because of their diversity, wide distribution, specificity to vegetation type, rapid response to perturbation, taxonomic tractability, statistically significant abundance and ease of sampling, they have been considered useful organisms to monitor environmental changes. The present work is result of a survey on butterfly fauna of Sawanga-Vithoba Lake region. For the observations of the species transect of 1 km long and 5 m wide was followed. Butterflies were primarily identified directly in the field or, following photography. Study was carried out for one year. Total 28 species of butterfly at Sawanga Vithoba lake area under five different families were observed. Most of the species were common. Two rare species were observed in this region. Butterfly exhibits seasonal variation in distribution of species at four stations of Sawanga Vithoba lake. In monsoon total number of species was more than in winter and summer. Few species of butterfly such as Papilio machaon (Linnaeus), Parnara guttata (Brener and Grey). Cepora nerissa (Fabricius), Pieris brassicae (Linnaeus), Junonia almana (Linnaeus), Junonia lemonias (Linnaeus), Phalanta phalantha (Drury) and Acraea terpsicore were not observed in summer. Much similar species of butterfly are observed at four stations of Sawanga Vithoba Lake area. Species richness of few species such as Catochrysops strabo, Eurema hecabe (Linnaeus), Pseudozizeeria maha (Kollar) is higher in all the seasons. Family Nymphalidae is the most represented family at Sawanga Vithoba lake region district Amravati.
