Since 2 of my female D tityus have passed away, I wanted to try to use them as practice for pinning or maybe resin encapsulation. Neither are particularly great specimens, with missing tarsi from constant burrowing during egg laying, but they're my first rhinos, so there is some sentimental value.
Both died on their backs (I had leaves in their containers to help against this, but guess you can't win 'em all), and had the very dark elytra D tityus get when in high humidity. I let them dry out in my garage for a couple of weeks, and the color has come back a bit, but their elytra are still very dull and dark. I'm hoping it's just residual sub left on their elytra.
What is the best method for cleaning specimens for pinning? Or is there any decent safe way to bring out their color? I'd rather not damage them.
