For butterflies and moths I think it's fairly straightforward - I'm relaxing specimens that are more interesting so people can view the quality when buying. For things that are ex-pupa or where I'm confident in the quality, I'll have a display specimen and they can then be purchased in paper.
For other insects, I'm not 100% sure about what to do. Especially for I guess "rarer" specimens that I have like Cetoniinae from Africa and larger Lucanidae from SE Asia. Would you expect each specimen to be spread for you to choose from? Or would viewing a sample in the display case and then choosing from specimens still on cardboard be acceptable? In some cases, I may only have one exemplar, but for others, I may have as many as 10-20.
For the less expensive ones, I am leaning towards having a display case with a sample of each spread and then people can pick from specimens still set on cardboard - is that customary?
I'd appreciate a bit of guidance from the more experienced collectors here
