Objectives:

The objective of this study is to identify butterflies and to contribute the butterfly checklist of Bangladesh with established a permanent database.

Methodology:

The study was conducted in Chuadanga during November 2011 to April 2014. The district is situated in western part of Bangladesh. This area is covered with cultivated land, wetland and homestead vegetation include trees, herbs, shrubs, grasses and climbers which support butterflies species for their larval food, nectar feeding and resting. The climate is monosonic. The mean monthly temperature was the highest 35⁰C in May and the lowest 8⁰C in January. The highest rainfall was recorded in May (330 mm) and the lowest in December (05 mm). The average humidity varied from 95.0% to 55.0%. The habitats were documented randomly by visual observations, walks, opportunistic observations and butterfly species were also photo-documented by Nikon Coolpix P100, Canon DSLR 1100D and 55-250 mm lens during the study period. Species identity, taxonomy and nomenclature were confirmed with the help of the books by Evans (1932), Wynter-Blyth (1957), Marshall and de Niceville (1883), Bingham(1905), Kunte (2000), Kehimkar (2008), Singh (2010) and Kunte et al (2012). Butterflies observed were categorized into four groups (Very common >10, Common 6-10, Uncommon <3-5, Rare <2) based on their relative number during the period. I sampled butterflies in several possible habitats such as flower gardens, fruit gardens, beside the railway bush, roadside bush, agricultural fields, homestead vegetation and open land etc. Each species was noted and photographed instantly.
