Reminds me of how the Allies estimated the production capacity of German tanks during WW2: https://medium.com/dataseries/how-data-science-gave-the-alli...
Great read! In comparison, I have to wonder why the "intelligence estimates" were so bad/severe over estimates.

You can send fake reports if you think the other side is listening. You can move or mock material if you think the other side is watching. You can feed false information if you are captured.

They are for sale, for cheap, in every drug store.
The number of presumably Europeans in here citing screens blocking light as a reason for not installing screens makes me think maybe those screens are pretty low quality?

They do not, and it's unfathomable why. One of the first things I did after moving to Berlin was put screens on our major windows. My European friends constantly complain about insects coming in (wasps are a big offender in Berlin - and technically you can't kill them) but for some reason never just put up a screen.
> They do not, and it's unfathomable why. Our current windows pivot in the middle which makes a fixed screen impossible. (They do have a "pane inside" mode which would let you put a screen on the outside but we're 3 floors up and it would be a bit tricky, not to mention inconvenient when the temperature drops.)

Fun idea, but presumably there is a big bias in that some flies will be easier to catch for various reasons. I suppose lots of population studies on birds, cetaceans or whatever have this bias, since you can't just slap a quadrat down and catch everything. In fact with these more advanced animals, perhaps they're harder to observe a second time since they've learned to be wary of humans.
Right, if you're measuring long enough that predators eating some of the flies could be an issue, then you'd want to mark them with something only visible under a blacklight, or similarly "neutral", so it doesn't introduce a bias.
In my statistics class we were taught a technique for estimating the number of flies in a barn. You capture a fixed size sample of flies, e.g. 100, and give them each a little white dot on the back, then release them all back in the barn. Leave them to mingle for a while, then capture another fixed number of flies, e.g. 100. If 5 of them have a white dot on them, then you estimate that the 100 flies you captured orig…

Why can't you kill wasps?
This calls it a 'myth', but really concludes that it's hyperbole arbitrarily calling out wasps; they're technically a protected species and you could be fined but.. almost certainly not going to happen for one or two wasps bothering you at a cafe or whatever? https://medium.com/@sophanemwise/the-wasp-killing-myth-in-ge...
Wasps are the usual example because it's legal to kill flies/mosquitoes and no one wants to kill the other protected insects like bumblebees. The wasps in Berlin are common and pretty aggressive, and have free rein in an awful lot of the chain backeries.

I found two flies in my house, marked them, then later found two more flies without marks. I think this means the population of flies in my house is infinite.
