Fireflies

There is something going on with fireflies and trees lately. When I walk the dog after dark, it's not a matter of waiting for the occasional firefly sighting. There are fireflies all through the trees, flashing in beautifully random patterns, like Christmas lights escaped into the wild. They seem as likely to be signalling to the stars as to the glowworms in the grass below. Watching as I walk, I can't tell from simple observation whether any of the stars are flashing back.
