Schmetterlings-Häuschen bauen

I have, for the last 4 or 5 years sent USA Papilio pupa to a contact in the EU who raises them in what I'd call a conservatory,

Papilio polyxenes, trolius ,Eurytides marcellus. I'm not aware of issues with the butterflies being damaged trying to escape.

I suppose there are a number of variables with any particular captive environment.
