Midge bugs, also called fish flies, invade Gimli, Man. for a few days each year at the start of summer. The larvae hatch on the water and swarms of bugs fly inland becoming a feast for the gulls. The bugs gather in large plumes that look like forest fire smoke from a distance, and townspeople have to shovel the dead carcasses away after the plague. An amazing glimpse into lakeside living on the shores of Lake Winnipeg.
