Sometimes they just don't fold their wings properly when molting, and they get stuck that way. Often happens if they're disturbed during the molting process.
You and me both. Been wanting these for years, but every attempt I've made to get them has ended in failure. 😭 At this point forget breeding them, I just wanna see a live adult before I die. 🥲
It seems this is a highland species that wants temps no higher than 23-25C° for incubating their oothecae. So I think you have them too warm.
They are also sensitive to excessive moisture as oothecae, and prefer very high air humidity, but low surface moisture.
I have pure bernhardti, and what are supposedly real petiveriana as well. Waiting for the latter to establish still, getting babies from the bernhardti now though so those will be available soonish.
