There is a gall like object or exoskeleton attached to a plant stem I have found. At first I thought it was a cicada but it is not. The object cannot be identified by me. Attached are some pictures of it. Could you identify it?

  • $\begingroup$ It's a praying mantis egg case. It won't have "legs" until the eggs hatch. If you're lucky and watchful, you'll see a bunch of tiny praying mantises around it (if you put it back) and the shrubs around it in late spring. $\endgroup$ Apr 2, 2018 at 2:57

It seems to me the ootheca of a mantis before larvae eclosion. You can read more about it here.

  • $\begingroup$ google.es/search?q=mantis+ootheca. If you think that is the exuvia (outer skin) of an insect because it is a thin paperlike membrane with nothing inside, then it is not a mantis ootheca because it would need to have the egg chambers inside to be one. It can not be appreciated from the photo. $\endgroup$ Apr 1, 2018 at 23:43
  • $\begingroup$ Are they easy to find? $\endgroup$

  • $\begingroup$ I used to find about a dozen egg cases a year on my property in PA, Sometimes more. Yet we only had three, maybe four adults active that I could find. $\endgroup$ Apr 4, 2018 at 6:40
