What are these? I've had many different coloured cars over the years, but this white one attracts loads of these bugs / flies. It's a bloody nuisance!! I washed it yesterday and this was the result!!
I have similar problems with yellow cars. It's mating season - they think it's a big flower and they'll congregate there and shag on your car. No long term damage, and they get blown off when you drive away.
