“We have also recorded more than 100 other insect species in the lake. It is home to a variety of grass hoppers, jewel beetle, leaf eating beetle, dung beetle, tortoise beetle, long horned beetle and ground beetle. There may be more than 400 species of insects and an extensive study is required to understand the complete profile of insects in the locality. Already different groups of research teams have taken up study in this regard. There is even a possibility to find some new species of insects in the lake,” said D Vasanthakumar, insect researcher from Zoological Survey of India.
