My first mantis (Stagmomantis californica) I had since L1 spouted wings. My records show she is now L8 unless I missed a molt. Do wings appear at the last molt or is there one more? Here are some pictures taken 3 days after the molt and you can see the wings are not laying flat. Is this normal?
I've seen a few where the wings dried puffy. The only time I've read that it's been a problem is they sometimes get in the way when mating, but the mantises usually find a way around it fairly quickly.
