same with insects. The most obvious change is long distance driving: you used to have to stop every few hundred kilometers to wash dead insects of your windscreen, with soapy water and a squeegee. It used to be a popular visual gag in movies, people on bikes or riding outside trains, would have faces full of bugs. Now, I can do an 8 hour drive without even using my wipers.
Street lights at dusk and dawn used to be surrounded by swarms of moths, beetles, and other insects. They've all gone now.
