They look like Sesbania clown weevils Eudiagogus rosenschoeldi to me.

I have seen hundreds of the three species of these and all of them have been on sesbania. It appears these are on the same plant also. The leaves in the foreground show the same damage I am used to seeing.

I was wondering what that plant was and you named it for me! I looked it up on Wikipedia and that's it! Thanks so much for your help!

Please keep in mind that I am not 100% sure of the ID on the weevils. John and Jane have been at this a lot longer than I and I have never known them to get an ID incorrect...

I really would like to get a top view on these guys if you could. That would make it much easier to get an accurate identification.

from you?? :)
We are also just amateur volunteers. We simply matched your image to some in the guide. Ron actually knows more about these critters than we, since we never see them. More images from different aspects would be good while we wait for one of the coleopterists to give you a firm ID.

:)

Seems like they are always sideways... but maybe something in one of these other shots will help:


A couple of older, but closer pictures:


Horribly blurry...

1) The pink tint helped push my thoughts to Eudiagogus rosenschoeldi
-and-
2) When I see these, I almost always see all three species on the same plant at the same time.

Please see HERE for images of all three species.

It looks to me that the above thumbnails are all Eudiagogus pulcher because of the break in the black stripe along the elytral margin and the overall color.

The next thumb has Eudiagogus pulcher and Eudiagogus maryae with the E. maryae being the smaller of the two.

That link must be broken. I get a blank page.
Searching Google for images of Eudiagogus rosenschoeldi makes me think that the pink is wrong. It's nearly impossible to google some of these names and get images.

The reason googling a name like "Eudiagogus rosenschoeldi" doesn't work well when searching for images is it looks for images named exactly that. I don't think many people would name their picture like that.

Every picture of Eudiagogus rosenschoeldi that I have seen has jagged lines seperating the black from the base color where both other species have straight lines.

E. rosenschoeldi

E. ulcher

Both of the above links are to Rice University images.

Again, the reason I was going with E. rosenschoeldi on your original image was the lack of a top view and the pink tint.
