Has anyone else seen a butterfly do this?
I was riding on the local rail trail the other day when a pretty good sized butterfly--not sure what kind, probably some kind of fritillary--flew through my spokes. He just floated right through my front wheel from right to left, without missing a wing flap and without any apparent injury--passed through the wheel like a ghost and kept on going.
I still don't quite see how that was possible, but I saw it clearly. Admittedly, I wasn't going fast--not much more than walking speed--but look at the spokes on a bike going at that speed. They're whizzing by awfully fast--a lot faster, I would have thought, than a butterfly in flight.
The C&V element here that I was riding my Gitane TdF. And I know, photos or it didn't happen, but I'm not that quick.

Obviously a daredevil butterfly, possibly on drugs. 🤔😁
On a similar note, ever been buzzed by a hummingbird? Those guys are pretty crazy, too. 😁

Yeah, one of my hopes for this thread is that no one will post "after" photos of a chipmunk that tried and failed to do that.

These are not the spokes you are looking for.

I had a pigeon go through my front wheel once… he didn’t come out the other side… just disappeared into a cloud of feathers.

Don Juan would have told Carlitos that the butterfly was able to do that because it had "the personal power"

Is the reference to drugs in regards to the butterfly? Or the rider? That would be a pretty cool thing to observe. My guess, they are so light and flexible that the deflection of air from the spokes pushes them right on through.

Then again, there may have been other forces as work, I have a vague memory of my high school chemistry teacher, Mr. Plati, telling the class that because apparently solid objects consisted mostly of empty space between atomic particles, it was theoretically possible--if everything lined up just right--that a brick thrown at a glass window might just pass right through it without damage. He did say that that kind of thing didn't happen very often.

Good thing for the OP it wasn't an iron butterfly....
Buddy of mine and I once had a chipmunk run between the front & rear wheels of the tandem we were riding, Glacial Drumlin Trail outside of Deerfield WI. I just did the math in my head, and estimate he (?) had about 0.4 seconds to make the move.
There was a rash of helmet dive-bombs by red-wing blackbirds on the Military Ridge Trail, just west of Verona WI, about 15 years ago. Most of those reporting the incidents had red, or partly-red, helmets.

Per the interwebs, butterflies can fly at speeds between 5-12 mph. 1 mph = 63360 in/per hr. An hour is 3600 seconds. So dividing 63360 by 3600 gives you an equivalent rate for 1 mph of 17.6 in/sec. 17.6 X 5 (factor of speed)= 88 in/sec; 17.6 X 12 (factor of speed)= 211 in/sec. A standard butterfly is 2" long, so he could cover that 2" distance in 2"/88" per sec or .022 seconds (at a rate of 5 mph) or 2/211= about .01 seconds (at 12 mph rate).
A bicycle traveling at 10 mph, with a 700c size wheel makes 123 rev/minute, or 123/60= 2.05 rev/sec. In .022 seconds (slow butterfly) that wheel makes .045 revs, or 16.2 degrees of revolution ; in .01 seconds (fast butterfly) makes .021 revolutions or 7.5 degrees of revolution.
Yeah, I think he could squeeze through... but, to answer your question, "no, I've never seen it".

Yes, I've seen a butterfly do that; the key is he has to go through the wheel pretty close to the ground. The forward motion of the spokes is directly proportional to the distance from the ground at the point of measurement; the patch of tire that touches the road, after all, is stationary; the top of the tire is going twice the speed of the bicycle.
I've also seen butterflies do that with predictably messy outcome. Oops.
I saw a squirrel do that once. No, wait, that's not quite right. My father in law, who was riding immediately behind me, is the one who saw it. I only saw the squirrel fly up into the air just to the left side of my front wheel, where he was subsequently booted by my left foot and pedal as it continued its circular path around the crank. The squirrel landed a few feet in front of my wheel and continued its path across the road, to the sound of uproarious laughter from the bicycle behind me.

Not a butterfly but I've had a pigeon fly through my bike frame as I was riding along. Here in London there's loads of them, and as strong fliers with street smarts they leave it until the last possible second before getting out of the way. This one I almost ran over as it was walking along the road, I thought he was walking away but he suddenly veered back around and took flight like the Millenium Falcon, straight through my frame. I did catch it with my legs as it did it, but he corrected and styled it out and flew off. Proper Top Gun.

For the record, I was not on drugs that afternoon. Not sure about the butterfly. Your theory about air deflecting from the spokes sounds plausible to me.
Then again, there may have been other forces as work, I have a vague memory of my high school chemistry teacher, Mr. Plati, telling the class that because apparently solid objects consisted mostly of empty space between atomic particles, it was theoretically possible--if everything lined up just right--that a brick thrown at a glass window might just pass right through it without damage. He did say that that kind of thing didn't happen very often.

I'm on my 1987 Trek Antelope and a chipmunk darts out in front of me, panics, and starts to turn back.
I run over it with my front wheel.
Feeling a bit guilty I turn around to check on it.
He's dead, and the tracks from the center rib of my front tire lined up perfectly with the stripes on his back.
A burial with full honors commenced.

I looked back and saw the cat make it to the other side of the road, tail intact. ...Cat must have been going almost 20mph(?) (it's a short-wheelbase motorcycle).
It might have hit the exhaust pipes, but I didn't feel it.
Gad, I still have that bike!
