A Different Bordered Plant Bug? 2b - Stenomacra marginella

A Different Bordered Plant Bug? 2b - Stenomacra marginella
Prescott, Yavapai County, Arizona, USA
May 29, 2008
I went back to where I had recorded this submission and photographed this adult massing under cottonwood trees in a broad floodplain. I haven't been able to find a match. See also .

They are back again
by the thousands

Moved from Stenomacra.


Moved from True Bugs.

Moving to Largidae
Here is this species on BugGuide:

Here is the page with the Maryland Department of Agriculture identification story.

Here is the Smithsonian plate. See #22; legs don't appear red as with other specimens in this collection.

Here is a Swedish Museum of Natural History specimen: even though the specimen is labled Theraneis the url is Stenomacra cliens.

ITIS has Stenomacra as an accepted taxa with two accepted species (there may be more, just not listed) and places it in largidae (larginae).

I'm amazed that there is so little concordant information on this species that seemed so abundant to me. I'll move to largidae but someone might consider a Stenomacra cliens species page.

I think Eric is right
in assuming these are stainers. Wing tip venation is as typical for that family.

why I don't think it's a stainer
Boris and Eric certainly have much much more experience than I do, but I will still be surprised if this turns out to be a stainer. To me the stainer seems shorter and a bit stouter. Also the first segment of the antenna on the stainer seems shorter than the one in this picture. That being said, I won't be surprised if I end up wrong. :)

I don't know if it's a Largus or not, but there are a few more images of Largus found on the 19th row of images from the top on this site. Drawing #22 looks close sort of??? Acutally #23 might be closer. That's Largus marginella.

Bugs Under Cottonwoods
Lynette's resource is pretty amazing. I think row 23, 2nd plate over, #22, Resthenia schumanni is pretty close. I scoured around for Stenomacra, Resthenia and Prepops seems close too but didn't turn-up much. I'll see if I can visit these bugs again to see if there's more mature pigmentation, and then come at this fresh.

Thank you.

Return Trip
I was able to return to the bugs but they looked the same they did a week ago. I can post images if that would help. I even have images of molting in progress. The Aydin Orstan specimen is very close (head & antennae may be different) but there is no identification on the specimen, however I haven't finished following-up all the leads. (Check-out the Western Screech-Owl from nearby over at Mike's site.)

Other images
I assume stenomacra is an older(?) name? See this also
