I will admit I have no clue where to put this, but I felt I had to post it somewhere. This happened to me today, November 5th.
I was splitting firewood, as I have been doing for the past few weeks as its getting colder here (North Eastern Saskatchewan, Canada). I split a few
blocks as I always do, and on one block I noticed that a butterfly was in the center of the block of wood. A solid block ! No pockets of space, no
bark it could have been in, no signs of it living there at all. But there it was stuck to the wood where I had just split it. I thought, hmm
interesting, it almost looked like dry wood bark, i thought it was dead. I tapped the block of wood with the axe and the butterfly came to life. It
was a living butterfly from a solid block of wood.
I still cannot explain how it managed to survive. First off I thought, OK, i imagined it was in the wood, it must have flown here and landed on the
split wood. But if that's the case, I still want to know how it has survived the temperatures here. There is snow on the ground ! It was snowing
when I found it ! Its been -5 celcius, with the wind, nights get down to -12 celcius.
Could the butterfly survive these sustained periods of cold? This is the only one I have seen by the way.
Anyways, I ran back to the house and grabbed my digital camera for some quick shots. My focus is bad, but you get the picture.
Now I have read threads on this very site about animals springing to life after coming out of solid objects and I always found it to be silly, but
this really made me think.
Was it alive in the piece of wood?
I've never heard of those before.
