As dusk descended on my campsite on the outskirts of St Louis, Missouri, flickers of floating light caught my eye.
When one drew closer, I realised it was a firefly with a flaming tail that switched on and off. I had never seen fireflies before and the novelty wasn’t lost on me as I scanned the growing darkness with eager eyes and childlike fascination.
The small twinkling lights looked like the stars had jumped from the sky and were now playing among the lush green carpet. I felt like I was at the centre of the universe in the warm evening air.
