I have two females of this species. I pinned one fresh and the entire right elytra blackened afterwards, the same thing happened with the other one that was bone dry. Does anyone else have this problem? I'm not sure why it does that.

You can soak them in acetone and the natural color will return. I've heard that soaking in alcohol works also. There have been several discussions about this on this forum.

I use multiple acetone baths. I also prop the edges of the elytra up abt 1-2mms w toothpick pieces so as to allow the acetone to reach in. Males will have it happen as well. I’ve done one beetle three different times and others not all. Mine usually are dipped for 12-24 hours, but have done longer.

The other guys are the experts. But having used acetone on a number of S. Diana females I was amazed . Personally I immersed the entire butterfly for 24 hours and then let it dry for maybe 30 minutes then stuck it in a Riker Mount to minimize chances of wing curling . Then re-pinned specimens. Worked great for me .
