Preying Mantis Oothecae

Preying Mantis Oothecae

These are Oothecae or egg cases of Preying Mantids.  Each will release up to several hundred hatchling mantids when they are ready to emerge.

Thank you for the answer-it’s been stumping me for about 6months. I am so glad we found your web site. Keep up the awesome work.
Thanks from Denver.
