Fireflies are flooding Ottawa with light this summer

The wet spring that brought us bumper crops of mosquitoes and deer flies has also left us a kinder gift: This is an amazing summer for fireflies.

Everyone in town is noticing them as they flicker in parks and back yards after dark.

In Lanark County, former University of Ottawa ecology professor Paul Keddy said his home is surrounded by the little glowing bugs too.

The reason: They have more to eat this year. More food means more fireflies.

“Both young and adult fireflies feed on snails, slugs, worms and soft-bodied insects including the larvae of other bugs like mosquitoes. Some adults don’t feed while others eat pollen and/or nectar and are therefore considered a pollinator,” says the Canadian Wildlife Federation.
