Thank you! That's interesting. We have fireflies too, but they are beetles, and we call them glow worms. They cam be seen between June and August, or a bit earlier, nothing is certain any more, it's warmer overall. Between field and creek, where I live, many could be seen, not so many any more recently, perhaps it's too dry, or too many pesticides, or too much light. People with their stupid flickering LED lights in their gardens don't only disturb birds. Sorry, ramble rant...
