This photo, created as a composite of many images, shows the hidden world of fireflies says photographer Albert Kao:
A human sitting outside on a summer night likely appreciates the beauty of flickering fireflies but considers the flashing to be random. It is anything but. For some species, males and female fireflies signal to each other in a multi-step mating ritual, while other species use flashes to lure and devour hapless interlopers. Each species has a unique flash pattern: some are short and punctuated, while others are prolonged. Several species of fireflies may co-exist in the same habitat, creating a cacophony of signals as individuals search in the darkness for others. I took many images of firefly flashes in a small clearing and created a composite image in order to visualize the complex, and largely hidden, world of fireflies.
