Why Do Lightning Bugs Glow?
As June evenings settle in, tiny green flashes begin to appear over meadows, marshes, and forest clearings. Fireflies are back. Fireflies use their flashing light to attract mates. Different species have different flash patterns, and some even use their glow to trick other fireflies into coming close, only to eat them! Best places to see them: Near wetlands (they love damp, open spaces) and along forest edges. On still, humid nights, the warmer and calmer the air, the more fireflies you'll see.
