Asked November 6, 2016, 4:27 PM EST

We have been seeing this strange cocoon like thing on our bed markers and other sturdy places around our farm. Have you seen it before? Thank you, Margret Harburg

Lucky you. Those are egg cases of praying mantids.Even though they're considered to be beneficial predator insects in gardens and landscapes, they don't discriminate between good insects or bad. See this http://ipm.ucanr.edu/PMG/NE/mantids.html
