Summer nights set fireflies free. Before they appear in late May or June, they have spent most of their lives underground, a full year growing to maturity. Then the long summer days must be spent in hiding -- under bushes and in the grass, dining on earthworms and snails. All for the sake of two short weeks of abbreviated nights, the only objective being to mate and start the cycle again.
And so they rise into the night, traveling in packs of thousands, blinking to each other, occasionally flashing in unison, their behavior a delight to youthful hearts everywhere.
