Beautiful preparation, as always, Xiaoyu!

The spread wings of my specimens sometimes convolve after few months for no apparent reason. Have you ever observe this problem?

There is the same problem occured in my specimens.

I think the dry wings absorb water from the air and so they change shape.Because the thickness of wings is not the same, the wings convolve.

Keep specimens in dry condition,it does help.

You just gave me an idea. I never thought of pinning them upside down. That should help with flattening the wings.
