Several publications suggest that the coloration of pupae in Papilionidae is controlled by environmental factors.

collector,
Thanks for your response

Thank you both. Fortunately, I've just found my old paper stock from BioQuip. The watermarks are unreadable. Here is the product description from the BQ, see the attachment, just in case someone is interested in this technical issue. I remember how the labels on the Ornithopterae in my grandad's col...

Can anyone tell me what kind of paper should I order and where?
In the past, I used an "acid-free, heavy stock" (or something like that)

Thanks in advance!

Thanks, Kuni

Thanks to everyone, who replied.
As I said, I used Elmer's glue. So far the chrysalides look fine.
I'll update you on the results.

I have a few Nymphalidae chrysalids, detached from the substrate.

Please help!

Dear wollastoni,
What is the max kb/gb for the pictures?
Thanks
