Sad and frightening to hear. Funny though but here in southern Sweden and Denmark I've had the opposite experience. Sometime around 2018 I started noticing a lot of fireflies, in a park in the middle of a major city. Which was not normal to me. Since then I've noticed them almost every summer. And on vacation in Denmark it's the same thing, the air is alive with life. It has its downsides too because there are more ticks than ever too. A lot of cities here have started leaving grassy areas uncut, they just cut a path through it for people to walk on. Also Copenhagen has started building "walls" of twigs, encased in a wire mesh. These walls act as safe havens for all sorts of insects and small creatures.
