Praying Mantis Egg Case

Quick Overview

Watch a cloud of tiny praying mantises (or nymphs) emerge from a Praying Mantis Egg Case. 

Availability: In stock

Product Name Price Qty
Live Praying Mantis Egg Case (#700)
Live Praying Mantis Egg Case Certificate for shipment LATER (#1100)


See 75 to 200 Baby Mantises (also called Nymphs) emerge from a Praying Mantis Egg Case (Ootheca)! Once they hatch, release all but one or two Praying Mantises, as they are carnivorous and may eat their siblings. Initially, you can feed your Praying Mantises tiny insects like aphids. As your Mantids grow it is necessary to switch to larger fare like flies and crickets. 

Praying Mantises are fascinating predators; they can turn their heads 180 degrees  from side to side and their excellent eyesight can detect movement up to 60 feet away. Some Mantises even become tame enough to accept food from your fingers.

Insect Lore recommends that you feed and observe your Praying Mantises for a short while and then release them to forage for garden pests.

Egg cases are available mid-January to the end of June, while supplies last. Allow 4 to 10 weeks to hatch

Cases sold individually. Instruction and information sheet included. Food for the hatchlings not included.

  1. Amazing Experience Review by Mantis Madness - Crystal Lake, IL

    I did this with my daughters and daycare kids and they were so excited about process. One egg pod gave us hundreds of praying mantis. Each child brought some home to their gardens, leaving me with about a 100. We did this 2 years ago and every year we all have a pod and we spot adults in our yard. This project has engaged 3year olds all the way to adults for over two years! Last year their was an adult on our car, we didn't know it until customers coming out of bookstore were surrounding our car (we were watching from restaurant window). When my husband went outside to see what was wrong, it was just excitement over "strange bug". And about 6 people walked away seeing a praying mantis for first and with your website! Love science!!!!!! (Posted on 5/20/14)

  2. Wonderful experience Review by Cherie - Holly Springs, North Carolina

    I purchased two egg cases and the both hatched within a few weeks of arrival. The second even hatched on Mother's Day! I should have probably kept them in the frig for a few weeks though. The temperature needs to be in the 70's for the best results. We had a great time helping each of the nymphs to find a safe plant to sit on. We kept 10 nymphs and cared for them daily because we could bring them in and out as the weather permitted. We are hoping to see them get a little larger before we free them so they have a better chance of survival. We were only going to keep two but the others didn't want to leave the butterfly habitats.

  3. Awesome! Review by A Happy Home Daycare - Sneads Ferry, NC

    I get an egg every year for my daycare kids. They love it! I also buy "wingless fruit flies" from a supplier online. That way when the the praying mantis hatch, their food is already hear waiting for them. We usually keep a few, but release most of them about an hour after they hatch. Needless to say, you can find a praying mantis in our back yard anytime during the summer! (Posted on 5/6/14)

  4. Awesome Experiance Review by Allen - Lockport, newyork

    This was our 2nd year with the mantis egg sacks. Last year we missed the hatching as it happened overnight. we released them into different areas of our yard. some stayed around for a week or two, and we even had some adults around the yard later in the summer. This years egg sack hatched just today 5-3-2014 Ironically at our 6 year old sons birthday party they started hatching, it was a wonderful Experience for all both young and Old , amazing how this many mantises came out of this tiny egg sack. thank you Insect lore.

  5. Awesome!! Review by Kimberly - Round Lake, Illinois

    I have been hatching Mantis eggs with my children for 7 years. For the last 4 I have purchased them from Insect Lore. They have always been great. Only one year did we get only a handful. Otherwise we have always gotten a minimum of 150 mantises from each egg. My children love them. We always wait about 8-10 hours after they finish hatching to release them. They are dry by then and ready to hunt. All of the kids in my neighborhood love to hold them and release them into our garden. They don't always like to leave the container they hatch in. There are always some that need to be shaken out. It is a great experience all around. (Posted on 4/24/14)

  6. Loved It! Review by Nessa - Stockton, CA

    Our egg case hatched in two weeks and we had such a blast watching and raising them. I'm not sure why some of the other users have had bad experiences. I felt that all the information that was included with our kit was very helpful. The kids and I unpacked, set up, and then read through all of the printed brochures. Our local pet/feed store did not sell small enough fruit flies but we have been able to find plenty of small afids in our backyard garden for the few mantis bugs that we kept in the net home. The rest have taken quite wonderfully to our back yard. The kids enjoy searching for and finding them out in the garden. Thank you Insectlore for bring science to our kids and making it FUN!

  7. GReat experience; Tough for people far north to do Review by Angela - Two Harbors, MN

    This was a fun expereince last year for my kids. We had two egg cases and had tons of baby mantis! It took about 3 weeks for the first one to hatch and 5 for the other one. Sadly, it was far too cold outside here in northern Minnesota to let them go outside. So, we let the few surviors go on various house plants and hoped they would survive on the gnats that tend to live in my house plants. They didn't survive though. I would really love for a few of them to make it to adulthood so they could live in my garden. There's just not enough super tiny prey available here until later June. We had the same problem with our butterflies last year too due to unseasonable cold weather and an inability to release them. Hopefully this season will be better for the butterflies but I'm not sure the mantis will work for us because they are only available at a time of year we are still locked in the cold. :-(

  8. Totally awesome! Review by Liluofthevalley - Bristow, Virginia

    My kids (2&4) did this last year. 200 tiny baby pray mantises were released on our azalea bushes out front. This fall I saw a full sized adult had returned and layed a new egg case in the azaleas! I highly recommend doing this with your children. There's lots of info online to guide the less informed.

  9. Needed food or guidance. Review by Lydia - Arvada, Colorado

    The praying mantises hatched successfully and it was gratifying to watch them. I only wish there had been some more guidance for me or food for them. They just sat in the cage and didn't show any signs of eating each other. After about three days, per the instructions, we started letting them go to prevent them from eating each other. We opened the cage and they wouldn't leave. I shook some out one day in various parts of the yard - the lawn, by rose bushes, by flower beds. They just sat there seeming stunned. The rest still wouldn't leave the cage with the flap open. Weren't they hungry? The next day, the rest in the cage were dead. Nobody ate anything as far as I could tell. It was a little sad as I started to think of them as my responsibility. Wondering what I did wrong. If I could have more information about the creatures' needs next time, I would buy it again. For now, I am sticking with butterflies. (Posted on 11/10/13)

  10. okay!!! Review by hass - Valley Steam, NY

    I bought this product with great excitement and waited for over three weeks to get only ten mantises. I was extremely disappointed but still enjoyed the pleaser of raising one in my room. (Posted on 10/29/13)

  11. Oh, my goodness!!! Review by Mary - IfjQuzwA, qp6gxD6M

    Oh, my goodness!!! I just read your other post about the baeibs hatching. This is just AMAZING!! I am blown away that you actually caught her laying the sac!!! I would be doing backflips if I witnessed this and/or the baeibs hatching. Thank you so much for sharing this amazing wonder of God's creation!!!! I find egg sacs every year in my garden but have never had the privilege of witnessing either laying or hatching. (Posted on 9/10/13)

  12. Praying Mantis Egg Case Review by Sheila - Elyria, Ohio

    This is extremely wonderful. A Fun great project. The kids watched as each baby praying mantis emerged and began eating one another. It was really awesome. The kids holding the egg, holding the babies it was a very wonderful absolute great experience. I gave it 3 stars only because I wish insect lore supplied food for the babies when they emerge or direct us to where to buy food for them because unfortunately we had to let them go outside where hopefully they could find food. Overall all though it was a great experience and we would do this again. (Posted on 9/9/13)
