Step 1: The Egg Case

Picture of The Egg Case
There are usually 10-400 eggs in the ootheca (egg case)
and they are very small. When they hatch they need food small enough to catch and eat, as with baby clownfish, food is needed to be smaller and the size where it can be eaten. The flies would be added in a test tube catch's worth to a quart container of a few babies.

Step 2: Hatchlings

Picture of Hatchlings
Gently move the babies to a container large enough for them all, or several small containers. Then make sure to have an air hole, and a moist cotton ball down in there, so they can molt properly. You will have milions of babies. Feed them 5 or so per baby mantid a day.Make sure there aren't any puddles of water as they will drown in them. They need vertical things like sticks and such to help with their molt, because they use gravity to help pull them out.If they gnaw at your finger, they are thirsty.........When they are going to molt they won't eat and dead skins will be around the tank.

-In first grade a friend brought in a egg case and it hatched during the night. That day there were mantids everywhere. Even in our desks and tables!

are mantids dangerous? like, do they bite or scratch things?
elite14 (author)  JBowmanDIY3 years ago
Relatively safe, I don't know of any harmful cases.
I just found about 25 baby mantis in my daughter's bedroom crawling on her floor. Any idea how they are getting in? I caught most and released them back outside but still have about 10 in a container. Is it better just to release them or try to raise them until they are grown and can fend for themselves.

First off there probably living in the house because there are a lot of crickets, grasshoppers, etc. So I would dispose of all the mantises by hand then bomb the house with RID, and that doesn't work you might want to patch up the hole so they can't swarm into your girl's room
if there hungry and stuff they might fight with their little weed-whacker hands but it doesn't hurt i promise
Ah it depends on the species I think. For instance the New Zealand and South African species don't but some of the others may. The only place soft enough for their jaws to get around is your lips, and the malaysian species can probably hurt your fingers, but I don't think they are poisonous overall. So generally I'd have to say no they are not dangerous (unless to each other mmm nom nom).

They can fly, they are attracted to windows, The ones in My project are beasts and around 4 inches long and can't fly yet. When they are done with their 6th molt they can fly. They don't bite you.....or pinch unless provoked or if they feel threatened, they run away more often. I had one that loved to cling to my shirt and it was no problem. They will bite/pinch you if you mi-handle them, squeeze them (just a little too much by accident), or appear threatening to them (they fly away. Hope this answers your question
how long do they live
elite14 (author)  dontkillpenguins3 years ago
Around a year or so, they live over summer, breed, and die with new hatchlings to replace them the next year.

Me and my dad always thought prey mantises are aliens LOL
I have 2 prey mantis's i caught them one male and one female i have them in separate cages but im not sure if the female is pregnant and was wonderin if anyone could let me know that if she is pregnant if i have to keep the babys is another cage or if they are ok to stay in the same one as her?
If you keep the babies(if she's pregnant by the way) in a separate tank the babies might die so if you don't want to raise them put them in separate tanks
The female is usually obvious if she is pregnant and has yet to lay an egg sack. The belly usually becomes a lot more pronounced in its bulge. After she lays one egg the belly will usually return just about back to normal, but you have to be careful because they can lay more than one (my boyfriend assured me ours wasn't pregnant and she layed her egg on the top of our curtain ><).

The babies should be okay with the mother before they hatch, but when they do it's a good idea to remove the female or she will eat her babies. Although the mum may not live to see her babies born, as depending on the species they don't have a very long life span.

Hope that helps :p. Have fun. The little ones are cute!!

We had some praying mantis hatch on a poolside basketball hoop.  We made this video of them.  They are so cool.

So happy to find this website. I am sitting here watching "our" praying mantis that we found about a month ago during one of our dog walks. She is currently in the process of making a nest for her eggs. I told my husband that I t hought she had a fat belly. Unfortunately, she chose not to make her nest on one of the twigs in her habitat but on the lid. So how do I disengage her nest without harming the babies? Can I place the nest outside on our screened-in porch? The holes in the lid are large enough for the hatch to crawl through, and we don't want any lose babies in the house. I've read that a hatch can take 1-3 months, but in our heated home I'm concerned it may be sooner. I sure would love some advice.
elite14 (author)  1boxermom4 years ago
Wow I haven't been back for a while,
Is it possible to put a fine mesh screen over it?
I'd do that, the eggs could be damaged from removing them
from the lid, Theye grow quicker in the heat, in the fridge they slow down on growth. If the lid is just a cheap one, you could cut around it and move it.
Sorry everyone

Ok. So we have two praying mantises outside in tanks (kept seperately). I have just found two teeny tiny babies in my house. Only two...where could they be coming from? The two big girls were not found at my house, so I have no idea if we have any in our yard, etc. Could they be coming in on my dog? I havent seen any sign of babies near the tanks outside, so dont think they came from our "pets". I am new to the Mantis craze, so have no idea....what now?
The babies are probably coming from an egg sack on the fence or wall of the house, or even sometimes from somewhere down the road, as they can travel quite a bit. I'm not sure about travelling in on the dog, as I don't know whether they would feel comfortable doing that, being as small as they are. If you do keep the babies, they should be kept separate from your pets, or they may be munched on >>, especially since yours are both females. Kept them fed with little prey like fruit flies until they get bigger, but make sure they eat or they will try to eat each other, when they get bigger you can move them on to bigger food. Hope that helps.
I love mantis :D especially ones that listen to coheed and cambria! great instructable btw.

I have a moth problem in my room can letting 1 or 2 go in my room to fix it
I think it wouldn't hurt to try - my mantis devoured a moth twice its size!
elite14 (author)  spenfisher5 years ago
I don't really know. Could try one and see if it fixes that, then put it in it's cage so it won't get crushed accidentally overnight
