They are all butterflies, obviously. The first one might be a limenitid, second a Papilio.
What are you going to do with them for your project?
...You're going to set them, surely?
If so, please do so - so you can post photos of the uppersides as well.
Also: where are they from?
Scale would also be useful, especially for the 3rd one.
im a photographer and have created different patterens using these specimiens. i have no idea how to set them without breaking them and no idea where theyre from as aquired them from ebay. thanks for the help
