Praying Mantis are strictly seasonal. All Mantis Ootheca are available for shipping in April and May. 

This listing is for pre-order only. If you complete a sale involving Mantis ootheca, the earliest we can ship them to you will be April 2018, possibly May 2018. By placing an order, you agree to this. 

Included is one ootheca, or egg case, of Tenodera sinensis, the Chinese praying mantis, along with full instructions. Average hatch time on an egg case is 2-6 weeks, but please allow up to 10 weeks for your manits to hatch.

Upon emergence, mantis require food items of around 1-2 mm in size. We offer flightless fruit flies (sold separately) to meet their needs until they are large enough to be fed small crickets. A fruit fly culture or two will sustain your mantis for around one month. If you are buying an ootheca for greenhouse or garden use (natural insect control), hang it in the region you experience the most infestation of 1-2 mm sized pests (such as aphids). 

Initially, you can hatch and rear your mantis in a communal habitat. Make sure that they have many rough surfaces to climb on and hang from to molt. After about 2-3 weeks, you must be prepared to house them separately as they do become cannibalistic around that point!

Chinese praying mantis are the only mantis species approved for Agricultural purposes in Canada, so can be released outdoors in the garden once the weather is warm enough (typically never before the May Long weekend). 

This species grows slowly, but with proper care and consideration, they will reach lengths of around 4 inches and can live about 8 months. Mantis make absolutely fantastic display animals, and if your hand-feed them from a young age, they will recognise you when you enter the room and come to your hand for treats. Mantis are very visual predators, and the way they observe you right back as you observe them is unlike any of the other invertebrate groups we work with. 

Please note: We do not sell single mantis, or adult mantis. 


Sorry, no refunds. Remember: you are dealing with living animals. Nature is not perfect; in the wild, survival rates would naturally be very low, with only around 5% of insects surviving to adulthood. In captivity, you should expect a much higher rate of 70%-90% survival. Please incorporate these statistics into your lesson plan, and never assign a single insect to a single participant, as some of them will not make it. It is always ideal to observe insects as a population.

SHIPPING: Please review your invoice carefully to ensure there are no mistakes in the information we have been given for you. Ensure your order has been translated correctly. Butterfly Wings N' Wishes is not responsible for shipment delay or failure due to incorrect information on the invoice. If an order is delivered to an incorrect location or is returned to us due to these issues, we may charge an adjustment fee in event that your parcel's delivery must be corrected.

Please be aware that mantis ootheca are NOT guaranteed. Mantis ootheca may take up to 10 weeks to hatch, although a typical hatch time is between the 2 and 5 week mark. Female mantis will lay ootheca whether they are fertilized or not, and there is no way for us to tell if they are going to be viable at the point of sale. It is normal for around 5% of ootheca to be infertile, and we have no way of guaranteeing success rates once environmental variables are introduced. 

By agreeing to do business with us you hereby agree to abide by all terms and conditions as presented by Butterfly Wings N' Wishes Ltd.
