A seed pod, but still searching for an ID.....
I often saw them and wondered where they came from.
Had them under the stereo a couple of times, about 4mm I guess.

EDIT: your 'myth explode' post gave away the size: slightly lager than 3mm.

EDIT 2: Is it the seed pod from a Birch?

I was thinking someone may have thought an insect; it does have wings and antennae!

Yes, it's from a White Birch, Betula papyrifera (also known as Paper Birch and Canoe Birch).

From "Trees in Canada" "Each fruit a small flat 1-seeded 2-winged nutlet (often erroneously called a seed), .... and bearing 2 withered thread-like stigmas at the tip."

Gah, missed this, I would have got this one! (well not the species!)

I shook some out from a ripe seedhead a couple of months ago from the silver birch in our garden
