See a Summer's Worth of Fireflies In Under Two Minutes
This compilation of photos featuring fireflies is from 2011, but there's nothing dated about a field full of bioluminescent beetles (they're not really flies). As summer turns sweltering, these lightning bugs break out their flashy mating dances each dusk. Viewed in one sitting, it's the perfect dose of summer escapism at your desk.
