There is an invisible world at Sanjay Gandhi National Park (SGNP) that remains dormant in the summer. It consists of thousands of micro-fauna such as various bugs and insects that stay beneath the ground when the sun is oppressive. But once the monsoon hits, they come out of their homes to feast on the flowers that blossom in the rain. This makes it the best time to observe them, and a trail this weekend aims to do exactly that.

It will take place at SGNP's Nagla Block since that's an area that is still largely untouched by picnickers and other human invaders. Organiser Sachin Rane tells us, "The only visitors who usually head there are photographers and naturalists. This is because the mirco-fauna there is really interesting compared to the rest of the park. There are also many different types of birds and butterflies, of which the yam fly is especially beautiful. My team and I have in fact spotted at least 125 varieties of butterflies there, including one called guava blue."
