Are lightning bugs scared by lightning?

Driving home last night with all of us in the car, there was a pretty impressive lightning storm in the distance, with some awesome ligtning. One of the kids asked if lightning bugs got scared of the lightning. My answer was to pretend to be a lightning bug (in a high buggy voice) -

"Pretty flashing lightning, you look like just my type. I think I love you. I light my butt to show that I love you." (with appropriate behind wagging).

The kids thought that was hilarious, and we've had a lot of "I light my butt for you" since then.
