That is a daunting image. Reminds me of a time Fanatic and I did an event way up in Quebec, plagued by blackflies. Sort of a rogaine, set up for 36 hours but we had been assigned a third partner who ran out of gas, so we headed in and were only out for about 16 hours or so. The headnets only were useful for keeping the inside and the outside blackflies apart. I had strips around the waist and the wrists where they got into clothing gaps and I had blue scars that looked like tattoos there for about six months. Really a character building experience.
