Corbett Tiger Reserve (CTR) located in state Uttarakhand is the first protected area established for in-situ conservation of biodiversity in India. Despite its national importance, there exists lacunae in knowledge on butterflies, important from the viewpoints of effective planning and implementation of conservation actions in the CTR. Using standardized methods, the present study conducted between 2013 to 2014 was aimed to record butterfly species composition and distribution in different sampling regimes of the CTR in relation to habitat types and disturbances. Study revealed a total of 2621 individual butterflies of 56 species under 5 families. Among them, 24 species belong to the Nymphalidae family, 14 species to the Pieridae, 9 species to the Lycaenidae, 5 species to the Papilionidae and 4 species to the Hesperiidae. 50% of the total species were recorded as ubiquitous and 30 species are new records to the CTR. Species such as Catopsilia pomona (Fabricius), Papilio polytes (Cramer), Eurema hecabe (Linnaeus), Catopsilia pyranthe (Linnaeus) were most abundant and Athyma zeroca (Moore), Sarangesa purendra (Moore), Cyrestis thyodamas (Boisduval), Polyura agraria (Swinhoe) were least abundant species. Variations in the calculated diversity indices across the seasons were observed; wherein, summer season exhibited maximum value for Shannon-Diversity index, followed by late monsoon and early winter. Lowest diversity of butterflies was observed during the periods of late winter. Presence of seven species under the Indian Wildlife Protection Act and five species as rare, substantiate the importance of pristine conditions prevailing in the protected landscape of the reserve. Ongoing tourism activities and habitat alterations threatening butterfly diversity and ecological integrity of the CTR, were also discussed.

印度北部Corbett老虎保护区不同生境的蝴蝶群落分布模式

位于北阿坎德邦州的科比特老虎保护区（CTR）是第一个为原位建立的保护区保护印度的生物多样性。尽管它具有国家重要性，但对蝴蝶的知识仍然存在不足，从有效计划和实施CTR中的保护行动的角度来看很重要。使用标准化方法，本研究于2013年至2014年之间进行，旨在记录与生境类型和干扰相关的CTR不同采样方案中的蝴蝶种类组成和分布。研究发现，共有5个科的5621种蝴蝶共2621只。其中，N蝶科有24种，the科有14种，,科有9种，,蝶科有5种，蜘蛛科有4种。总物种的50％被记录为普遍存在，其中30个是CTR的新记录。物种如Catopsilia pomona（Fabricius），Papilio polytes（Cramer），Eurema hecabe（Linnaeus），Catopsilia pyranthe（Linnaeus）最多，而Athyma zeroca（Moore），Sarangesa purendra（Moore），Cyrestis thyodamas（Boisduval），Polyura agraria（Swinhoe）是最不丰富的物种。观察到整个季节计算得出的多样性指数存在变化；其中，夏季表现出香农多样性指数的最大值，其次是季风后期和初冬。在冬末期间，蝴蝶的多样性最低。根据《印度野生动物保护法》的规定，有七个物种和五个稀有物种的存在，证明了保护区受保护的原始条件的重要性。还讨论了正在进行的旅游活动和栖息地的改变，威胁到CTR蝴蝶的多样性和生态完整性。
