We found thes crusty pupa thing on our fence. We live near Denver, Colorado. Does anyone know what it is.
Signature: Thank you for your help.
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.
