Hi my girlfriend had 14 mantis all of different types .All have mooted fine till this last month were 3 have failed to molt properly ever by being too low or on the bottom of tank . They have plenty of room in tank to hang on and high up , humidity is correct so don't know why this happened .any help would be appreciated

What species? And what stages?

One was a giant dead leaf not sure on the overs
If you could get the actual Latin names and more information about what nymph stage they are I would be more than happy to help you. I can’t do much without knowing the specific species and their stages because the husbandry varies between different species and stages in those species.

Deroplatys lobrata?
Ambient humidity isn’t as important as internal moisture. Even if the environment is humid, if the mantis is dehydrated then it won’t have enough internal water to push it out. Try spraying water in front of it or pipet some water on the moth and see if they dip their heads down to drink.
You can also examin if the mismolt is due to dehydration by if the legs ate stuck even when the abdomen is out. From my personal experience dehydrated mantis when molting will pull the abdomen out before the legs, and get stuck.

what are the enclosures like? I have major too high humidity concerns. these species have very different humidity requirements. So spraying them both twice A day would not work

Open mesh topped tub tanks about 30cm high and 15cm wide
Okay so for Parashendale affinis your humidity is way too high! Humididty in homes is usually around 30-50 percent, at least around me, and P. affinis does well IME right around 50% but I would say no more than 60%. So depending on where you live and time of year, your in home humidty, if its on the higher side, can be close to what budwings need. So spraying twice a day will for sure cause molting issues. you may only need to spray a couple times a week, if that. Maybe once a week, maybe not at all.

Deroplatys desiccata target humidty in my opinion is around 70-80%. So then spraying twice a day is likely too much even for them. I have never sprayed D. desiccata twice a day. I would monitor it and my inside humidity but I would say once a day should be good.

I have no idea what you mean by "membraccea". I searched that and found absolutely nothing.

What would be even better would better would be to post pictures of the set ups. Im not sure how big the holes are in the mesh, could be too large off a mesh. And I highly doubt it tried to molt on the ground it seems IMO much more likely that it somehow fell while attempting to molt.
If youre interested in keeping mantids I suggest you first monitor your home humidity levels and adjust how you keep your mantids according to that. I never spray on an absolute routine basis, and how often I do changes throughout the seasons here on the east coast of US.

I find that humidity is irrelevant for most mantids. Two mistings daily are enough. WHere are they molting from? What type of molting surface are you giving them? Are you only using the cloth lids, or do you use mesh lids? How big are the mantids? Is there anything in the way that the mantis could run into while molting? If your mantis is a larger individual(which the heirodula seems to be), then it's likely that the mantis couldn't get a good grip on a molting surface and fell. Pics of the enclosure would help. Also by "membraccea" I'm sure he means hierodula membranacea.

2 mistings daily is way too much for all 3!! They do not need that at all, any of the species. People mist mantids way too much, don’t encourage people keeping wet mantids

Don’t just spray to spray. It’s unnecessary. Especially twice a day for every species you have. That’s bad advice and incorrect husbandry.

I think it really depends on the species and size of the mantis. If you're talking about smaller nymphs/species like creobroter or odontomantis, 2-3 mistings per day is vital to keep them from dehydrating. Larger mantids, such as adult females, don't require as much but will still drink from water. Also, since mantids can't absorb any moisture from the air, I feel like misting them daily or twice a day provides them with an ample chance to hydrate themselves. The conditions where you actually keep your mantids is also important. If you live in a relatively dry area or if it's during winter, they can lose moisture quicker and it's better to provide them with more water. I've never really encountered issues with too much humidity for mantids and molting, the only problem I can think of is if you keep them too moist and with little ventilation. The stuffy conditions could quickly kill them, but I don't think it'd have any impact on the molt. Also based off of op's post, I think that it'd be better to redecorate the enclosures so that there's more sticks/decor towards the top so that they have ample molting space. Personally, I keep most of my mantids in 32 oz deli cups or larger contaienrs with a mesh/cloth lid with some fiberglass mesh wrapping around the interior of the container and they seem to do just fine.

creobroter or odontomantis
Yes but we’re not talking about those species. We’re talking about P. affinis and D. dessicata that absolutely do not need two mistings a day. He needs the correct husbandry for the species he owns. Not other species he doesn’t own.

I think his husbandry is fine. Looking back at the original post, it seems like the mantids were moting too close to the ground. If op can rearrange the decor so that it's more centered towards the top, that'd be better.

Yes but he should know what his inside humidity is and mist accordingly, never just blindly mist and guess. Mantids in nature

well we don’t know what his set ups look like. But IMO his husbandry is not correct, especially for P. affinis. I’ve kept budwings a lot and there have been times I’ve never sprayed them. He needs to learn where each species come from and more about specific husbandry for each. He’s keeping 3 very different mantids in exactly the same conditions, and spraying twice a day, just to spray. That’s not good husbandry cause he doesn’t know enough about them.

If you keep finding the mismolts on the floor or whatever, I would address the ceiling. You should glue fine mesh or coffee filters to the ceiling for better holds. I don't think it's a humidity thing in this instance.

And remember, the enclosure ceiling should have many inches of free space for the mantis to hang during molting. Overcrowding with branches and stuff is a no-no.
