Fireflies belong to the family Lampyridae, which is comprised of over 2k beetles. They are typically found in humid regions, and can be spotted en masse in the summertime in such regions. These glowing insects are known for their bioluminescence, which is a form of light produced by living organisms.

The phenomenon of synchronized flashing by fireflies is known as “bioluminescent synchrony,” and scientists still do not fully understand it. However, it is believed to be a mating ritual in which the males use their flashing lights to attract females. When the females respond, the males will change the pattern of their flashes to signal their readiness to mate.

In some species, though, females take advantage of these patterns and signal males from another species. The males are lured in and the female then eats him.

The Kunthakulam bird sanctuary is one of the best places in India to witness this incredible display of nature. The Reserve is home to a variety of bird species, and visitors can also see other wildlife, such as deer, and monkeys. The fireflies typically start to light up around sunset and continue throughout the night.
