Early in the week we tore down our arbor and fence and discovered this cocoon attached to a fence post behind the foliage. We live near Modesto, CA in the central valley. We have been unable to identify what will come out of this cocoon once the insect immerges – can you help? It is approx. 1 inch long and has scales like a snake. The exterior is very "tough". It has maroon striped markings on each side with a cream color filling out the remaining exterior. My photos are a bit fuzzy – couldn’t get my digital to focus for a closer shot. Any assistance you can provide would be appreciated! My children and I are perplexed.
I would like to do more research before giving you a definite answer, but it looks more like an egg case than a cocoon. It might be a preying mantis egg case known as an Ootheca. I will get back to you.
Thank you – as you can see, I’m not up on bug terminology. A mantis would be wonderful.
