Take a closer look at this one.

I believe this is a female of Idiostatus, perhaps I. apollo or I. goedeni. The shape of the pronotum is wrong for Neduba, and the ovipositor seems a bit off to me too.

Compare with these at Singing Insects of North America.

Martha,

The picture of N. convexa is posted on SINA here . Tom Walker would appreciate it if you would check it out and to email him if you note any corrections or improvements that should be made or if you have a higher resolution version that you would like to have posted on SINA.

Use of photo

Lynette, Of course. Thomas Walker may use this photo for his SINA web site. Just give me credit! Martha Schraml, Manton CA. He must request to use it for any other purpose. I'm happy to share. So many of you share your knowledge with me.

Martha,

would you consider letting Thomas Walker use your photo for his website, SINA? If this turns out to be a female convexa, it will be that site's first image as well. See this page. I think he will be willing to give us an expert opinion on this, so I'm going to email him.

Shieldbacked katydid.

This is a female katydid in the genus Neduba. The classification has changed rather recently, so I'm not sure which species this is. Most species have very restricted ranges, though, so it should be easy to determine. Please see the "Singing Insects of North America" website, and look at the range maps for each Neduba species, and see if you can't pin it down.

Thank you so much! I did try to ID it by local. There seems to be two. But no pictures of females. I really appreciate your comments.

I vote for Neduba convexa

If you look closely at the maps for Neduba convexa and Neduba diabolica, it will become apparent that N. diabolica is found in the Coast Ranges and probably gets no closer than Mendocino County and part of Trinity County.

More importantly, there are images of females of both species if you look hard enough:
Neduba convexa and Neduba diabolica

The female convexa has the differently-colored area down the back, while the female diabolica doesn't. I don't know the actual technical details for separating the two species (I'm no expert, anyway), but that looks pretty suggestive to me.

thank you

Hi Chuck,
Thank you for guiding me to Cal Photos. I will certainly refer to that site in the future. What a great picture of Nebuda convexa!
