“How are they going to eat, how are they going to survive, if all you’ve got is concrete?” said Gregoire, 48. “I guess they were decimated, because I don’t see them anymore.”
However, far from development, Firefly Watch observers like Steve Irvine still enjoy dazzling firefly displays.
Irvine, 57, has lived for more than three decades in a rural area of Ontario about 250km north of Toronto filled with fields and marshes. It’s a feast for firefly lovers.
Summertime visitors can step outside just after dusk and find themselves surrounded by tens of thousands of fireflies, blinking greenish-gold to a flickering orange.
“The fields around here are just alive with sparking light — it’s just magic. There’s countless thousands of them in the air. It’s just amazing,” Irvine said.
