Founder and the first president of the Butterfly Conservation Society of Sri Lanka, Himesh was an irrigation engineer by profession and a graduate from the University of Moratuwa. He has been a nature lover since his childhood.
Himesh has engaged in leading researches in the fields of butterflies, birds and fish and has published many research papers in academic journals. He is the author of the book “A Guide to the Common Butterflies of Sri Lanka” and one of the co-authors of the book “A Pocket Guide to the Butterflies of Sri Lanka”. He has an in-depth knowledge on birds, fish, butterflies and plants. His love for plants has taken him a long distance in the field of Sri Lankan flora by finding some new plant species that are new to science (these are described in the “Illustrated Field Guide to the Flowers of Sri Lanka by Dr. J.J Vlas”) and has kept his mark in this field.
He was a member of the butterfly expert group that compiled the book “Red data listing -2012” and a member of the team for preparation of the Butterfly Conservation Action Plan-2013 that was conducted by the Biodiversity Secretariat. Being one of the pioneers in the field of the butterflies, Himesh has been playing a major role in butterfly conservation in Sri Lanka.
