Praying Mantis Ootheca Egg Case with Hatching Habitat Cup (TwoEgg Case) - Stem Education, Comes with a Transparent Habitat Cup, Egg Case Produces Approximately up to 400 Baby Nymphs (T Sinensis)

I purchased this to hatch baby mantises for my yard with fruit trees and other plants so they could grow and eat the bugs. As soon as I saw them in the cup, I put it outside with the lid off in among my plants in shade, and let them go. Hopefully they will grow and make it in my space; since I kept them in the house at 74 degrees to incubate, and it is over 100 in AZ now, the change in environment may be hard on them. Shade helps, and something is getting watered every day, so I am hoping that they can adapt and thrive…

I purchased 2 ootheca and separated them into 2 vented containers. Very gently, I hot glued the stems onto slightly larger sticks so they can hang. Everything was packaged well and arrived when expected. The only thing I might suggest is to include instructions on the direction they should be suspended. I may be wrong about this. Ignore me if so. I usually keep 1 or 2 nymphs and release the others in the garden after they grow a bit. Make sure you have fruit flys on hand to feed them. I will check back after they hatch.Edited: well, that didn’t take long. 4 days after receiving them, one of my ootheca hatched out about 200 nymphs. I wasn’t prepared! I had to run to Sedona PetSmart and grab 2 canisters of wingless fruit flies to feed them. I sprayed and fed them the next morning. They ate all of them (big shake of the fruit flies). I had separated the ootheca into 16oz.deli cups with vented lids. Everything was good until the morning of the 3rd day when about 3/4 of my nymphs were dead at the bottom of the container. Same thing with egg number 2 which hatched 3 days after the first batch. Guess I need to read up on them again! Peace!✌️

Was Sent to daughter in Florida. Arrived in just about 3 days. They started hatching exactly a week later. I also bought her a book and acrylic condo (my term). She is absolutely enjoying them in her garden. They are so tiny at this stage. So cute. She sends daily videos. Looking forward to their full size in about 3 mo. They say. Great purchase for your friend with a green thumb.

Follow up on reviews saying item was the size of 2 marbles, not the size of a lemon as pictured. After several weeks only one actually had viable eggs which produced no more than 30 babies over a 3 day period which I released 2 times a day around my property so they would not eat each other. The second pod appears to be a complete dud. Nothing emerged from it. Just an FYI to buyers, I did not get anywhere near 200 babies

Love them thanks. praying mantises are generally considered beneficial insects for gardens. They are voracious predators that consume a wide variety of garden pests, including aphids, caterpillars, and other soft-bodied insects. However, it's important to note that they are generalist predators, meaning they may also eat beneficial insects like butterflies and bumblebees

Oh, my babies came out. It's great that they hatched, and they’re doing wonderful things in the backyard.

One egg case hatched. One egg case appears to have had parasitic wasp or fly larvae on it and the maggots ate all of the mantis eggs in the second case.

This is the message I sent directly to the company, USMANTIS:Dear USMANTIS,I purchased two of your Chinese mantis oothecas on April 29th, 2025, and they arrived today. While I understand I ordered late in the season, which could explain them hatching during shipping, I encountered a few problems with the packaging that I’d like to bring to your attention.First, one of the oothecas had already hatched, which I half-expected, but unfortunately, the mantids were confined in a small paper bag that kept them from moving around properly. As a result, several of them did not survive. Secondly, the packaging itself was inadequate. The box wasn’t labeled as “Live Insects,” and there was very little packing material surrounding the cup to keep it secure. The top of the cup had come off, and some mantids had crawled out into the box.Additionally, the box was delivered to the mailbox, which is concerning, especially considering the high temperatures it likely reached inside. This left the oothecas exposed for a few hours, which could have contributed to some of the issues.I understand that mistakes can happen, but I would appreciate it if you could ensure better labeling and packaging in the future, especially for live insects. While I’m not dissatisfied with the insects themselves (as I still have one egg that has yet to hatch), I was disappointed by the delivery experience.Thank you for your attention to this matter, and for running a company that shares such marvelous creatures with the world! God bless.
