This simple rubber-legged foam beetle is one of my favorite flies for Arctic grayling. It's quick to tie so I don't mind losing one or two on snags. It's durable, so one fly can last a hundred fish or more. It never needs floatant to ride the surface well. Most importantly, it catches fish, although grayling often hit almost anything. The bold profile and attention-grabbing plop of the beetle, I think, draw fish from farther away than a more subtle fly might, and it often draws unusually savage strikes.
