My female just laid an egg case last night. How long will she live after laying, and what do I do now. She is in an exo-terra 12 x 12 x 18. The bad part is she put it right where the front doors come together.
Mantises are seasonal in the USA, so her lifespan will be drawing to an end as the season cools. She is capable of laying several more egg cases (oothecae) if she is fed well and kept at room temperature or better.
If you had this mantis in captivity since it was an adult, then the oothecae is worthless. Just like hens, female mantids will lay ooths whether fertile or not during egg season. There's always some chance a wild mantis has been fertilized though. She probably has less then a month to live by now.
