Naturalist Brian Keating on the differences between 2 fairytale-like bugs: damselflies and dragonflies

As summer comes to an end, many Albertans are rushing to enjoy some of the last days of camping weather, and you may notice the lack of mosquitos thanks to a special bug: the dragonfly.

Or at least that's what naturalist Brian Keatingnoticed when he stopped to see a cloud of dragonflies swarming above his head last week at a site west of Golden, B.C.

"The area is known for its wetlands, and there should have been a lot of mosquitoes around," Keating toldThe Homestretchon Monday.

Damselfly vs. dragonfly

Another bug zipping through the air and catching prey is thedamselfly the otherwise "daintier" version of the dragonfly, says Keating.

However, the insects arein different suborders.

Theyhave some differences. For example, dragonflies tend to hold their wings out when they land, whiledamselflies tend to fold them along their body when they're at rest.

Dragonflies are also faster, and are like bombers zooming through the air, says Keating.

"They can actually travel as fast as 50 kilometres an hour, whereas damselflies flit about almost like a little fairy creature. They're very delicate and graceful all around."

Some quick history

But don't underestimate these damselflies. Keating says theyare incredibly successful creatures that have held up for around 300 million years.

"Fossils show thattheir design really hasn't changed that much for all that time," he said. "I guess they're the ultimate predatory insect design."

The insectstarts its life cycle in the water as a nymphand manages to catch or capture preywith a mouth piececalled alabium.

"When they get close to prey, they shoot it outward and capture it with these pinchers and then bring it back to their face to feed on with their mouth parts," said the naturalist.

"They do a big job of cleaning up our ponds of mosquito larvae and other little creatures."

But they also may be the prey to some dragonflies, says Keating.

He says the carnivorous insectseat a wide variety of bugsranging from small midges,mosquitoes, butterflies andmoths.

Looking out for them in Alberta

Keating says you can see damselflies and dragonflies in Alberta.

He got in touch withChristine Hornung, who did her master's thesis on Albertadragonflies. Shelisted 49 species of dragonflies and 23 of damsels in the Prairie province.

"They're big, they're colourful. You can actually watch their behaviour, you can watch them return to the same perch like a flycatcher," said Keating.

Globally,there are5,600 species of dragons and 450 species of damsels so Alberta has a small but decent collection, the naturalist says.
