You might be crashing the biggest party in Japan's least populous region. Each summer, fireflies turn this forest in rural Tottori prefecture into their own glitzy nightclub. There's no telling which fireflies are the males in this shot but be assured they'll spend the mating season trying to flicker their way into the females' hearts.
Male fireflies search for mates by flashing a species-specific pattern that announces their availability to willing females. Interested females will reply with flash of their own.
