The information is based on a survey tour conducted during October 11-13, 2015. Around 0 the Palkot three sites were selected for the collection. Two sites were selected on Gobarsilli (22 53.058N, 0 0 0 Jalil Ahmad 084 39.229E), and one site was selected on Kura Pahar (22 51.621 N, 084 38.123 E).The collection Zoological Survey of India, survey and identification yielded a total of 89 species of Lepidoptera including 30 species of Butterflies Gangetic Plains Regional Centre, under 26 genera and 59 species of Moths under 42 genera. As far as Butterflies are concerned, Sector-8, Bahadurpur Housing Nymphalidae with 64% of total reported Butterflies dominated the group whereas, in moths, Erebidae Colony, Patna-800 026, Bihar, dominated with 73% of the collected moth species. India Keywords: Inventory, Lepidoptera, Jharkhand, Gumla, Palkot Wildlife Sanctuary 1. Introduction The Palkot Wildlife Sanctuary falls within the districts of Gumla and Simdega of state of 0 0 0 0 [1] Jharkhand and lies between 22 45’N and 23 N longitude and 84 30’E to 84 45E latitude . The National Highway no. 23 crosses and divides the sanctuary between two parts. The sanctuary received its status in the year 1990 vide Govt. Notification no. 1168 dated 22.03.1990. The total geographical area of the sanctuary is 182.83 sq. Km[1].The geography of Palkot WLS is unique by having several caves, cavities, crevice, dens, holes, and snags which forms a suitable habitat for wild animals. The sanctuary area is full of small hills and undulating land with intermittent plains in which habitation and agricultural land exist. Some of the hills are flat, others are with smooth curves and some having steep slopes. Plateau formation, locally known as ‘Pat’ is the most striking topographical feature of the track and is found on almost all hills in smaller or larger extent. The plains are rice producing fields. Patches of the land are also covered with Sal forest. There is usually three climatic seasons: the cold weather, the hot and rains. The cold weather sets in early November and lasts until about end of February. The hot weather corresponds to the period between ends of March to June [2]. The rain breaks at about the end of June and continues till the end of September. The average rainfall in Palkot Wildlife Sanctuary is about 1000 mm per year. The range of temperature varies according to the season during summer and it varies from 35– 40 degree whereas in winters it goes below 10 degree [2]. The forests of the sanctuary are classified according to the Champion and Seth [3]. The sanctuary comprises Northern tropical dry deciduous forest (Dry peninsular Sal - Type 5B/C), Northern dry mixed deciduous forest type 5B/C, Dry Sal scrub type Ds. The key floral components of the sanctuary are Sal and its associates like Asan, [2] Gamhar, Salai, Piar, Amla, Mahua, Kusum, Mango etc . The sanctuary area and its surroundings are not so healthy in vertebrate population. As per the forest department census of 1993, number of major vertebrate species is as follows: Leopards(05), Langur (80), Rhesus Macaque(500), Elephant(6), Sloth Bear(150), Wild Boar(240), Hyena(90), Wolf(50) and Jackal(200) besides number of Birds, Reptiles, [2] Amphibians, and Fishes .But, no data is available on the invertebrate diversity of Palkot WLS. The Zoological Survey of India, Gangetic Plains Regional Centre, Patna with the first Correspondence author as a leader of the party surveyed the sanctuary for the first time in October, 2015 for the Navneet Singh study of Lepidopterous fauna of the sanctuary. The Lepidopteran insects are among the best- Zoological Survey of India, Gangetic Plains Regional Centre, known insects, and are mainly recognized due to the body and wings covered with scales Sector-8, Bahadurpur Housing (modified and flattened hairs which give the butterflies and the moths their extraordinary Colony, Patna-800 026, Bihar, variety of colour patterns). Lepidopteran insects are broadly divided into Butterflies and India moths. ~ 654 ~ Journal of Entomology and Zoology Studies The latter includes most of the Lepidopteran species (about long term monitoring programmes will help in the enrichment 88%) and are nocturnal and often drably coloured.
