  SHORT INTRODUCTION TOBUTTERFLY 1. Butterfly is an important organism for this ecosystem. 2. The body part of a butterfly exists with head, thorax, abdomen, antenna, proboscis, compound eyes, segmented legs and colored wings. 3. The life cycle of butterfly includes four stages: egg, caterpillar, pupa & adult butterfly. 4. Behaviour of adult butterfly: Leaf Scratching Behaviour, Roosting Behaviour, Thermoregulation, Mud Paddling Behaviour Fig.1: Striped Tiger Fig.2: Common Jezebel Fig.3: Blue Tiger

  OBJECTIVE OF MYSTUDY To estimate the butterfly population at Eco-Park  Understanding distribution of butterfly species in Eco-Park To gain more knowledge about butterfly-host plant interaction Fig.4: Towny Coster

  MATERIAL & METHOD Observation period: October, 2022 to March, 2023  Sampling locality: Eco Park (Butterfly Garden)  Sampling technique: Point Count Data Analysis Fig.5: Eco Park Butterfly Garden (Source: Google Earth) This dissertation work was started with butterfly species identification for 2 months from October, 2022 to November, 2022. Common butterflies were identified by taking photos with the help of a Canon EOS 1500D camera and my mobile phone. Colour patterns, sizes, and shapes, as well as their designs, were considered in the identification of the species of butterflies with the help of my guide book "Butterflies of Buxa Tiger Reserve". Next I gained knowledge and observed the butterfly-host plant interactions for 2 months from December, 2022 to January, 2023. The sample data was collected over 2 months, with the help of point count method from February 2023 to March 2023 at last. This data was used to calculate relative abundance and Simpson’s Index.

  DISCUSSION  The maximumnumber of butterfly species was recorded from Papilionidae, Nymphalidae, Hesperiidae, Lycaenidae, and Pieridae.  The leaf-scratching behaviour of milkweed butterflies like the Striped Tiger, Blue Tiger was also studied.  Mimetic polymorphisms of Common Mime were observed in the study area.  This study can help us to devise butterfly conservation in future. Fig.10: Tailed jay  The present research has discussed the butterfly distribution of Eco park.
