A special type of firefly lights blue instead of white​

Spotting fireflies is one of the highlights of summer. If you happen to be in the Southern Appalachians, you might be able to catch a glimpse of a ghost firefly—and you'll know it if you see it because it will glow a unique blue-green shade instead of the standard white.
