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. 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. :-(

  2. 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.

  3. 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)

  4. 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)

  5. 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)

  6. 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)
