Not so sure about that. The issue may be less likely, but still can occur. We were bothered by biting flies at times in Idaho, Montana, and Wyoming on our Trans America tour. The blood suckers easily kept up at 18-20 mph and I have no doubt would have at higher speeds judging by how easily they closed the gap when dropped, They seemed adept at drafting. Even elite riders climb hard climbs slower than the pace we were getting bitten at.
I have also had flies biting in the Sierras on difficult mountain passes a few times.
