Small Butterfly & Microscopic Photo-Stacking

Hello,
A question for the lepidopterists: A small butterfly “expired” in my conservatory a few days ago. It is beautiful and in perfect condition, & I would like to photograph it through my stereo microscope. Is there a procedure (protocol?) for preparing such a specimen so that it doesn’t break when I try to move it? At the very least I need to flatten the wings which are folded vertically, if that makes sense, and the antennae are folded backwards parallel with the body.
Thank you for any advice.

Don’t mess with the antenae, they are certain to break off if you try to move them.

For the wings you can try to use a relaxing chamber

Thank you! I have all of that to hand. Watch this space!
