Albertans can expect healthy wasp, ant and beetle populations this year

Thanks to an unusually warm winter and spring, Albertans are shooing away more bugs, earlier than usual.

Insects emerging 3 to 4 weeks earlier than usual, says Olds College entomologist

It's not just Albertans who have been enjoying the mild winter and spring.

The bugs love it too.

The warmer temperatures have lured flying insects — such as wasps, bumblebees, ants and beetles — out of hiding.

"Easily three to four weeks earlier than normal," Ken Fry, an entomologist at Olds College, told the Calgary Eyeopener on Monday.

He said insects respond directly to "how hot or how cold it was" and not the calendar date.

Mild winters always translate into better survival rates for flying insects, like bumblebees, says Olds College entomologist Ken Fry. (Matthias A. Fürst)

Winter didn't kill them 

Normally, winter does a good job keeping the province's bug population at bay.

"That's the beauty of living in north temperate Alberta... It reduces a lot of the insects."

But Fry said it wasn't cold enough, for long enough, and Albertans should be prepared to do some serious swatting this summer.

In particular, he is expecting a higher yellow jacket wasp population because so many queens survived the winter.

That's bad news for those who are allergic to their stingers, but good news for gardeners.

"Those things are predators — they eat a lot of the caterpillars and grubs that feed on our plants."
