    OMG. That's what these are called. I was using my microscope and one of them flew into the double side tape I was using to hold the 0402 LED that I was working on. I was shocked that there was a bug that size and I caught it. It was half the 0402 LED. Lol. I recorded a video of it and man was it small. No one can see it if played at normal size. One zoomed in, you can see it. Fascinating.

    Weird i saw i hornet last year that i found weird it was the smallest hornet i have ever seen, i thought it was too small to be able to sting anyone and it appeared to only have a head and a stinger or what appeared to be one that was black. But again it was so tiny almost un seeable i wonder if it was some bigger type of these.

    Ok you keep saying that these things 'only' live a week but as far as i understand time dilation the size they live at would make their life seem longer. And they do not need food for this life so thats very advanced evolution imo.

    ..."feels supernatural! But it's not, of course." I don't know. I like to think this is all by design rather than random chance. But keep pretending these infinitely impressive biological discoveries have nothing to do with things outside observable science. The resolute attitude of many people, including scientists, have shifted a multitude of times, and are found to be standing on the foundation of fear and resentment, rather than infallible fact.

    Hank, you mean *"liquid"* where you say *"fluid".* Air and water are fluids, as both can flow. But a gas is not a liquid. For the small wasp, a gas behaves more like a liquid. ("fluid" is used at 2:50)
