I actually was sitting outside a few nights ago and realized that there was no more fireflies, and I couldn't remember the last time I had seen one. I used to go out all the time during summer as a kid to catch them, they would light up whole fields. That was just like 15 years ago. Pretty sobering realization

Yeah I feel the same. I recently felt pretty astonished after seeing them again once I went out in the woods.

German side streets are fairly dark already. This change will affect ‘large’ polluters, eg. floodlights in car parks, outside store areas, brightly lit buildings, etc. It is a very welcomed change. In our neighbourhood ppl knowingly plant flowers and leave grass grow ‘wild’ to support insects.

Yes, German streets are quite dark. Some villages even close the lights at midnight.

I do this too but I get bylaw visits from the city. Which cities?

Search for wildflower seed bomb mix, you shouldn't get in trouble for this. My mom used to do this every year when I lived in Germany, looks pretty and zero maintenance.

Cool idea, i have a garden and i hate maintaining it anyway.

This will be great for stargazing as well then!

I'm in Chicago (in a neighborhood close to downtown) and in previous years I'd hardly ever seen any fireflies. This year, they're everywhere -- in parks and even in trees on neighborhood streets. I understand fireflies are sensitive to light pollution. I can't imagine Chicago's any different from other major cities. COVID has people staying home a lot more but that has nothing to do with street lighting. I wonder wha…

We live rural southern Ontario and fireflies are usually just a single weekend or so at the end of June or beginning of July. But this year they went on for almost two months. They only just stopped about a week ago.

I'm not sure why it was a good season for them. Like you say, traffic, lighting, pesticide sprays on farms, all really the same despite COVID. Reduced air traffic I don't think would have an affect? Even after I sprayed my vineyard with insecticide to deal with japanese beetles they were fine, and continued to prosper in and around there.

It may just be that we've had an unusually hot dry year, I assume where you have as well. Maybe that's advantageous for them somehow?

The cynic in me views this as yet another attempt at fethishizing nature by people who choose to live in sterile urban environments. The problem with this type of fetishization is that it eventually combines with class privilege to produce narrow public policy that seldom promotes the public good.

Furthermore, those that live in less-urbanized less-sterile locales are painfully aware that nature and her army of insects always has the upper hand.

This is good; we've badly underestimated the cost of excess light pollution. Also good is using more LED street lamps that focus the light where we need it, rather than all over the place. Light pollution is bad, and street lights are very power hungry, with the old sodium lights consuming up to 0.25kWh per hour.

250W...

Which over an hour is 0.25kWh.

Used to be 100's or 1000's of them during the peak in summer where I lived. Now it's a handful. This is out in a rural area, so urban lighting doesn't explain the decline. If I had to wager money, I'd say it was a blight introduced by another insect. Around the same year I saw an invasion of Asian lady bugs, the firefly memories stop. There were literally millions and millions of those Asian lady bugs released or hat…

Plenty of fireflies in my yard. As prevalent as ever [1]. This is just an anecdote, but I give that anecdote as another person who lives in a somewhat rural location. Speaking of the lady bug explosion, this year they are incredibly rare [2]. Not sure why, but they went from being a massive nuisance to being a very rare sight (of any variety). Humans are absolutely having a calamitous effect on insect life in a varie…

it does seem like insect populations massively fluctuate for entirely natural reasons

Spot on, this is usually the real explanation for the typical 'I saw none'/'oh but I saw a bunch'/'I saw more than ever' rethoric applied to one single year or even multiple years of observations. Thinking of it, goes for basically all slowish trends related to nature. Unless you're approaching it scientifically, i.e. actual systematic counting which is hard btw, it's oh so easy to be fooled. That being said, see other post: yes fireflies are in decline (just like many other insects unfortunately) and light pollution is a factor.
