I have a female ghost that was paired with a male ~3 weeks ago. I left him in over night, and awoke to just wings on the bottom of the cage. I was wondering how long it would take to confirm whether or not it was a successful pairing. She had laid 3 oothecae,2 very small, a few days later. I decided to check in on them and opened one of the small ones, might not have been my most ethical move but I did it. There was very obviously liquid in the ootheca, after 3 weeks, so does that mean it was fertile?
