I love these tiny little LED flashlights. I brought Levi, my Weimaraner, out for his last call and noticed the fireflies were out.
I know female fireflies will often imitate the flash of those males who aren't doing the same flash they are so they can eat them rather then mate.
I watched for a bit and noticed a firefly would change their flash every little bit so I thought I'd have some fun with my LED and set up a flash pattern.
Sure enough it changed to my pattern so I did it again and it answered back.
By this time Levi was waiting at the door to go in so I flashed one more time and got a response and the last one I flashed was the same pattern that fly was doing in the beginning, it didn't respond that time.;)
