Ootheca - Tenodera angustipennis

Ootheca - Tenodera angustipennis
Schwenksville, Montgomery County, Pennsylvania, USA
June 18, 2008
Size: about 3cm
Is this the egg case of the European Mantis -- Mantis religiosa?


Tenodera aridifolia angustipennis?
Here is a picture of a Tenodera aridifolia angustipennis (I am guessing that the subspecies Tenodera aridifolia angustipennis listed on is the Narrow-winged Mantis but I am not sure if it is correct) ootheca a person showed me.
It looks different from a Stagmomantis carolina. Not all Tenodera sinensis are ball shaped. I had a female lay a huge ootheca that was kind of a shape of a mix of Stagmomantis carolina and Mantis religiosa. But that was a female from South Korea and most places say that the "King Mantids" (thats what they are called in Korean) are Tenodera aridifolia but a few places on the internet says they are Tenodera sinensis. The ones in Japan are Tenodera aridifolia right? There is a subspcies listed on, Tenodera airidifolia aridifolia that has a synonym Tenodera aridifolia japonica.

Moved from ID Request.

I believe it is Tenodera angu
I believe it is Tenodera angustipennis. It is very dark and old looking so I assume it is not freshly hatched. Think of a darker version of this with HOLES:

Hard to say...
I'd like to see a top view, as this may be S. carolina.

Mantid Egg Case
Hello John,

Sorry, can't look at the top -- imaged back in 2008. I live is the SE corner of PA where I always thought we had three mandids - Carolina, Praying and ubiquitous Chinese. I don't know that I've seen either of the first two -- let alone their egg cases. What would you be looking for on the top to make a distinction? My Borror, DeLong & Triplehorn makes no reference. Can you recommend a good site or text?

Thanks for your expertise,


Here is a Chinese mantid ootheca; note how the end is scalloped. These are also larger than those of S. carolina and M. religiosa.

This is S. carolina. Note the wide band along the top. This is what I'm looking for in your image.

M. religiosa. These are wider than S. carolina.

Egg Case
I believe I can recognize the Chinese. The other two are what present the problem. When you say the wide band at the top in that image, is the top at the right or left of the image? Or do you mean the whitish band running from left to right?

The off-color band running laterally down the top. In the linked photo it's a whitish color. In your pic it appears as a dark band on the left side as we're viewing it.

Sounds good

Thanks for your time and effort. I will take a much closer look this upcoming season. I'm a wildflower enthusiast and usually see the insects in connection. If you are ever in need of any images of wildflowers, I have many.
