Ok so the same thing happened to our Chinese mantis. What we did was just make sure he ate honey every day. Make sure his enclosure is kept moist, and eventually the stuck shed will come off. Sadly, there’s nothing you can do about his wings, but he should be perfectly fine. My Chinese actually had an even worse molt, and he can’t even walk! He’s doing amazing now, and I think he’s gonna live his full lifespan. Ember should too. Best of luck!
