There are eight firefly species in India, and they are the most abundant in the humid forests of the Sahyadris area that is a part of the Western Ghats mountain range. It is a perfect place for nighttime firefly-watching excursions. In just a couple of hours of drive from Mumbai, you can find some amazing natural landscapes that get even more beautiful after dusk, illuminated by thousands of miracle bugs. Some villages have started to hold annual firefly festivals during a few weeks before the start of the monsoon season (mid-May to mid-June) when fireflies are glowing to attract the opposite sex for mating. These extraordinary beetles live most of their life as larvae, throwing a short-lived but magnificent light display to reproduce and then die.
