Samarendra Nath Maulik (25 December 1881 in Tamluk – 9 July 1950 in Chelsea) was an Indian entomologist who worked at the Natural History Museum, London and specialized in the systematics of the leaf beetles.
A structure on the hind femur, particularly of flea beetles, and used in their leaping motion has sometimes been called as "Maulik's organ".
He studied physics, chemistry and mathematics at St Xavier's College, Calcutta but later became interested in biology from 1902 and started working in Assam, experimenting on the breeding of insects, particularly those feeding on tea plants.
He then spent some time at the Forest Research Institute in Dehra Dun and at the Indian Museum under Nelson Annandale.
[5][6] Maulik wrote on a wide range of topics, particularly in the Bangalore Mail and was known for his forceful but logical explication of ideas.
