Getting started with pinning specimens…

So I’ve collected a spotted lantern fly and what I think is a brood x cicada to work on. Both are in the freezer. I caught the latern fly live and the cicada looked to be freshly dead & undisturbed so I picked it up.

I have no idea what to do next. I’ve heard of the bodies decaying & rotting and horror stories of hatched eggs in the home and I would really love to avoid those things.

If anyone has any advice, a concise supplies list, or good resources to look at it would be greatly appreciated!
