I don’t know what else to call them. Drove over to Augusta this evening to buy some more wheels for my inline skates and before we left I cleaned off the dead insect residue from our last trip. About 1/2 way there I ran through a cloud of invisible bugs, you can’t see them in your headlights, but when they impact the windshield they leave behind a little puff of dust no bigger than a couple of millimeters in diameter.
When we came back out of the store I got out my bottle of Windex and a roll of paper towels and cleaned the windshield again. It lasted about 20 minutes before another swarm of bugs peppered the windshield again. I used the washer jets and the wipers to clean up this time, only to get another dusting within 5 minutes.
Squirt, squirt, wipe, wipe and this time we made it home without another encounter with the mysterious ghost bugs.
