Preventing brown stain (butterfly with diaper)

[Paul K]

I found few freshly emerged Delias descombesi few days ago, perfect A1 specimens. Upon inspecting them after 3 days I have noticed some of them are ruined by browns stain from abdomen   .
For now on I will be trying new system of inserting a tissue paper so it can absorb brown liquid.
I will also leave the specimen in envelope without removing the tissue when in relaxing box as the brown liquid may be released at that time.

I do the same thing! but I usually use normal glasine paper.

I always use tissue paper inside my enveloppes, but I put the butterfly inside a folded square of tissue paper, to avoid damaging the specimen by introducing it between the wings.

I often find the tissue paper full of grease, and the wings intact, so it works well.
