Oh yes. Lots of discussion on this issue if you conduct a search in the Forum. The original issue as I recall was not about the bugs, but the rocks. Someone posted that they caught a rock through the radiator which really messed with their vacation. Some people use a dog screen door protector. I bought a piece of expanded aluminum, cut to fit and painted it black. I did notice during last year's trip through Fallon, NV that we drove through a swarm of grasshoppers. Not one made it all the way to the radiator. I would be more paranoid of the rock or debris damage to the radiator.
