Monarch butterflies, the flashy insects that have been close to extinction for years, are suddenly flapping their orange-and-black wings all over our region in a population boom that has stunned biologists.

“In the last several years you look around and you (didn’t) see any of them. You could spend your entire summer hunting and see four. You can spend 10 minutes right now and see 40. It’s great,” said Jeremy Kerr, who studies butterflies at the University of Ottawa.
