I'm about to leave the East Coast to go to Stanford, and I don't want to live in a firefly-free world. I thought about trying to import them and have them breed, but apparently most species like humidity and standing water, which the Bay Area isn't too long on. I'm also not sure if they could find stuff to eat out West.
So robots are the logical solution. I realize it's going to be really hard to make something that small that's light enough to fly that blinks a light, has enough power to go for more than a few minutes, and can have the logic I'd like it to have. (In a perfect world, I'd like it to randomly roam campus for a few hours and then come back to where I launched them from.)
Also, my friend who's into robotics tells me that the US government has put a lot of money into robotic insects (for spying?) and not really gotten anywhere.
Nonetheless, someday I hope to make this happen, even if it doesn't quite have all of the features that it has in my mind.
