Is it possible to get a bad egg casing? I was able to bring a female tenodera aridfola sinenis that I bought at a pet store (for $30.00) to adulthood no problem. In fact was real proud of myself, so I decided to hatch an ooth of the same kind that I bought at a garden center. I left it out side in my garden for about a month before I brought it inside and hatched it in a aquarium. I was left with 14 nymphs by the end of it and as time goes on I have 9 left. The bugs that have made it to adulthood all but 1 have crumbled wings, 3 nymphs still left to molt. I am confused as to why this would happen. My first mantid was raised with no water or misting and is quite beautiful. These nymphs are misted every day so I think they are getting enough moisture. I live in Canada and the weather is cooling down but furnace is never lower than 72 F. so I think the temperature is good. The mantids that fell during the molt couldn't seem to hold on to the screening or in some cases to the sticks in the cages. I feed them everyday mosty crickets but some fly and moths when available. I hand feed so some eat every day and some don't, so I think I'm feeding them enough. I have since moved them into a private area. Now that I have a proper area maybe a quieter setting will be a better environment. This is turning into a bad experience. It's kinda unsettling to see so many mantids come out this way or die during a bad molt. (I did freezer 5)Especally if I am at fault. I am new to this hobby and do want to try and raise other breeds but it sounds like I could use some good advice. Thanks in advance.
