Fire Flies!!!!

We have a couple of fire flies in our tree tonight, even with the third floor!!!

We last saw them was three years ago. These are, to us, good sized ones, about a cm in length.

Yeah, I know most of you are totally used to them, but for former Southern Caifornia beach kids, this is exciting stuff!!

There used to be lots of them here before La Ropa and town got so built up. Looked like Christmas lights flying all around, and they would flash in rhythm. Something has disrupted their propagation. Hmmm, what's changed since 30 years ago?
