Lightning bugs.

We had two of them up under my porch roof Saturday night. Blinking quickly and chasing each other around. They use the light to locate mates.

I remember getting home right at dusk one night when we lived in Coatesville. It was the first time Spencer experienced them. We had a great time chasing them around in front of the house.

And several occasions when I was a child, collecting them in jars with my buddies. Hundreds of them.

When you hit one with your car's windshield, the bug splat glows green.
