Never been hit with a bug of any consequence while riding my bike, other than swallowing a couple.

I have taken some severe shots to the head on my motorcycle at 70 mph. About a month ago I had a bee smack my temple and lodge itself between my helmet and head. With its dying gasp of energy it stung me. I also once hit some large flying insect hard enough that it broke my sunglasses. I saw it coming in the last few milleseconds before impact, and then it felt like I'd been hit by a wild baseball pitch.
