Black flies (holy @#$%!!!)

The far north is definitely renowned for many things: cold temperatures, vast open landscapes, charismatic wildlife, and…biting flies. Entomologists have been collecting and studying black flies, horse/deer flies (apparently they are called “bulldogs” here – awesome!), and mosquitoes in the north for decades; they were one of the primary taxa of interest during the Northern Insect Survey of the mid-1900s.
My research group is no exception: we are busily trapping adult forms of these insects as well as their aquatic juvenile stages. There are many rivers, streams and beautiful waterfalls in this area, the moving waters of which are prime black fly territory.

Behold, black fly larvae:

Seriously, the quantity of larvae here is just mental. I pity the locals 2 or 3 weeks from now – eep! Yesterday we were pulling rocks out of the water that were entirely encrusted with fly pupae – we were actually watching some new flies emerge as we scraped other pupae of the rocks.
Other aquatic goodies are abundant too…dragonflies, damselflies, mayflies, stoneflies, caddisflies…the waters are incredibly productive.
