## Description

The USMANTIS T Sinensis Mantis Egg Cases provide a sustainable and educational way to enrich your garden or classroom. Each ootheca (egg case) is sourced responsibly from fields in the USA, guaranteeing freshness and viability. These mantis eggs ootheca hatch into T Sinensis mantises (Tenodera Sinensis), the largest mantis species in North America, recognized for their captivating size, colour, and role in maintaining garden ecosystems. T Sinensis mantises, "naturalized" in the USA since 1896, are essential contributors to biodiversity. They coexist harmoniously with beneficial, including ladybugs, and adapt well to gardens, greenhouses, orchards, and more. Hatch your mantis eggs ootheca indoors or outdoors with ease indoors, place the ootheca in a warm environment (70-85°F) and expect hatching in 2-6 weeks. Outdoors, secure the egg cases to plants or branches to protect against predators. Each egg case can yield up to 200 nymphs, which will disperse naturally. This kit includes a free hatching bag to ensure a controlled environment, whether for education or hobbyist purposes. The lifecycle of the T Sinensis mantis, from egg to adult, offers a unique opportunity to observe and learn about nature while contributing to your garden’s health and biodiversity. Elevate your gardening experience or educational project with the USMANTIS T Sinensis Mantis Egg Cases perfect for beginners and experts alike!

Review: Good, fast. - Hasn't hatched yet, but appears to be healthy.
Review: Ootheca infested with wasps - Not happy. Purchased two of these, not a cheap buy. Within a couple of days of opening them they are both teeming with insects that do not appear to be praying mantises, but instead parasitic wasps that are feeding on the ootheca. Seller must have an infestation wherever they are raising the mantises. Update: I froze these briefly to kill off the immense amount of parasitic wasps that hatched. With daily spritzing with distilled water as instructed, however, both ootheca developed mold within a week or so of purchase. I decided to hold out, and not return them, and approximately 6 weeks after purchase, 5 or 6 mantises hatched out. Definitely not worth what you pay. I would look at a different supplier.

*by M***E on May 17, 2025*

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.
