There were no fireflies this summer in eastern PA.... I was moving a lot the last decade and finally moved back to the northeast but by the time I did I guess they are pretty much all gone.
I'm really gonna miss fireflies. They were so pretty and such a peaceful part of a kinder world.
Writing about the VA area; I think they're mostly gone; I remember in the 90's they were everywhere all summer and now you see two or three every blue moon.
On a happier note I have noticed them in wilder regions like deep in the woods near a creek in almost normal numbers at dusk (and a lot more present out in rural areas I've driven through at night). So maybe if whatever's stressing their population to death subsides somehow at some point they'll bounce back at some indeterminate point in the future. That's about as optimistic as I can get about this sort of thing though.
It's fine that this is an old comment, this community doesn't have the interaction rate anyways so timely discussions aren't to be expected.
But hey that's nice that you saw some, I went into the suburbs and really only saw a few at a time. I definitely wouldn't feel comfortable putting any in jars like I did as a kid but hey maybe they can hold on for all the lights to go out.
