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…
I feel that I hear people say « we’re having a unusually hot dry year » every year...
Germany plans to dim lights at night to save insects

This. We bought a house in an HOA and I definitely had a moment where I was like, "Wait a minute, some guy bought this land, subdivided it, and created this HOA out of thin air and now here we are, 40 years later, living under that HOA he made up. None of the original owners even live here anymore!"
That’s not really any different than municipalities who tax and impose restrictions.

#473The best thing we can do on a personal level is to stop using broadleaf weedkillers like Scott's Weed and Feed and other herbicides like glyphosate (Roundup). I've been doing handyman work at my boss's house during COVID-19 and he has clover growing in his yard. He has a fair number of bees, certainly more than on my end of town which is all chemlawns. It's arguably ok to use a little weed killer by hand on dandelion…
They would describe it better than I can, but they can get away with e.g. just having plants that are repulsive to aphids (and plants that attracts insects that eat them).
They sometimes do have to use stuff like bordeaux mix but very rarely (if ever) use glyphosate.
Their garden is pretty amazing as a result. There are tons of birds (they have bird feeders) and insects. Bats in the summer as well.
Definitely how I see my garden if I ever get a house (I have been living in large cities all my adult life).

Unless there is actual data it’s probably best to not trust your memory. Every time you remember something the reality of it changes. Memory is lossy. Bias and selection are favored over improvement or precision of recall. Every recollection is inferior to the previous one. I have a few memories of extensive fire fly experiences back in the day. But when I really think about it, I don’t remember all the days and year…
Over the last 27 years, Insect biomass has dropped by more than 75% in protected areas in Germany. I don't think this is a memory issue. https://journals.plos.org/plosone/article?id=10.1371/journal...

So you provided actual data. That is good. That was exactly what they were asking - to use real data and not anecdotes from memory.

I'm not trying to hold myself up as an expert but on the other hand a lot of this stuff seems pretty obvious... Anything non-invasive? Anything not causing a serious public health risk? OK, mosquitoes are an obvious target here and I hate them with a passion but that doesn't mean we should kill everything just to get to them. Try reframing the question - which birds should you avoid killing? Which big cats are OK to shoot? Honest question - what is it about insects that feels like it's OK to wipe them out? Is it because they're so numerous? That simple extends the amount of time it's taking us to destroy them all, but we seem to be making good progress there.

I have an extremely hard time believing average citizens are having such a huge effect. This German law seems to have been spurred by some study saying that over the last few decades the flying insect population has dropped by a big percentage in Germany. Yet cannot find any information as to any adverse effect it had on anything. Nor is it obvious what exactly caused this drop. The logic here seems to be "insect pop…
And the counterargument is - let's keep killing them anyway? Why is that more logical?
It's the same logic as - fly/drive/heat less, to reduce carbon release; eat less meat to reduce land usage and methane release; etc.
It seems to me that maybe the primary reason we're doing so much damage to our planet is a combination of
a) for most people, personal convenience > planetary health, and b) as you say: "I have an extremely hard time believing average citizens are having such a huge effect"
The latter is especially pernicious - we are so successful as a species because, working together, we can achieve tremendous changes that aren't possible alone. But that potential for collective action can also have severely negative effects as well. Even a mountain can be leveled eventually if you keep chipping away at it. As an example of collective action, take a trip to Borneo and drive the 100km route from Tawau to Semporna - palm plantations literally as far as the eye can see in every direction, the whole route; it used to be rain forest. Individuals working together (whether deliberately or unknowingly) have a lot more power than they think.
Am I making sense? I'm not sure what's difficult to grasp about all this.

How would you stop them entering cities? It's not like an insect flies towards a city from a rural area then thinks "oh, no, shouldn't go there, I'll get zapped". If anything, we attract a lot of insect life with an abundance of light and free food. And then put out traps to kill them. > Since you seem to know about that, which bugs should one avoid killing?

I do not know but this is besides the point. I still do not see why we should protect the insects that are in the city as they do not bring us any benefit.
> Anything non-invasive? Anything not causing a serious public health risk?
Let me rephrase it, which bugs should one avoid killing because they benefit us directly or indirectly? Only bees come to my mind at this moment.
> which birds should you avoid killing?
The ones that benefit humans directly or indirectly.
> Which big cats are OK to shoot?
Big cats tend to not come to the cities so they do not really pose any danger to humans.
> Is it because they're so numerous?
In general they are gross, numerous, invasive, and they carry diseases.

The bees are an easy win - they do a lot of pollination work, but there are other insects that do that too. But is that all that's important? How about the oxygen you breathe or the nitrogen in the soil that nourishes the plants you eat or the rain that waters them? All these things depend on multiple complex cycles involving things like forests, the health of which depend on many other interconnected webs of life at all levels from mammal to microbe. It's Chesterton's Fence on a grand scale - if you don't know what it does, you really shouldn't remove it until you do know what it does. We're still working that out in many, many cases.
A lot of insects provide food for other animals - kill the insects, and we also kill all the things that feed on them. And there are certainly numerous other natural cycles and systems than those I outlined above (did you know that ocean microbes can seed cloud formation? https://news.agu.org/press-release/bacteria-feeding-on-arcti...) - these are just the ones that come to my mind as someone with an amateur interest in these things; I am, as I said, no expert.
> In general they are gross, numerous, invasive, and they carry diseases.
I understand why you might feel that way but, aside from the first (which is your opinion): the second, as we're discussing, is increasingly not the case; the third is generally only true where humans have transported a species to where it shouldn't be; and the fourth is really only true in very few cases - things like cockroaches and house flies, but even these fulfill important roles breaking down organic matter that would otherwise litter the surface of the planet, and thus returning nutrients into the soil, keeping it fertile. Cockroaches etc. are only a disease risk when they intersect with us, find a huge source of waste, and multiply excessively - and in those cases of course we have to deal with them.
> I still do not see why we should protect the insects that are in the city as they do not bring us any benefit.
An obvious reason that comes to mind is that cities as a black hole for insects act to decrease the overall population by simple diffusion.

After seeing this, I realized it was perhaps a bit unfair to assign so much blame to one company, and even bought a bag.
