Is that something the dealer would normally do at a routine service?
It seems a bit odd that the screen has such big holes in it as so many bugs just get sucked right in.

The air filter will stop bugs from getting into your engine, and you have to change it periodically. BMW changes it for you for free every 15k miles I believe, so don't worry. No, the dealer does not routinely pick bugs out of your air filter, they just change it entirely. It's non-reusable. Check your invoice, I believe that there should be work performed on your "air intake silencer" during your 1,200 mile service. That was the air filter.
