We're all about wetlands. Jump in.

Nov 1, 2018

Corixids, or water boatmen, are wetland insects with oars for legs and wings that can carry them kilometers from their homes when it's time to migrate.

Stephen Srayko, a PhD in biology candidate at the University of Saskatchewan, has been studying that migration for years. He watches as the corixids lift off from marshes and land on the shores of the North and South Saskatchewan Rivers in swarms during the fall.

There white sucker, longnose sucker, and goldeye fish feed on the massive influx of food. In turn, they provide sustenance to the rivers' game fish.

Srayko thinks the corixids provide a near invisible link between wetlands and the nearby rivers. They're one more reason why conserving wetlands helps a broader eco-system.
