Eucosma species - Aspermont, TX - Pelochrista

Eucosma species - Aspermont, TX - Pelochrista
Aspermont, Stonewall County, Texas, USA
June 18, 2016
Considering all the moths in the "silver-spotted" Eucosma group for which images exist online, I'd judge that the moth in this record seems at least as distinct from all of them as many are from each other. I hope there is a way to progress this ID!

Moved to Pelochrista
Moved from Eucosma aemulana.

I agree with Martin that this more likely to be P. agassizii or something close to it. Todd's image at MPG looks like a mistake. There are plenty of images of E. aemulana on the web and this does not look like it and there is nothing in that genus that I can see that looks like it. I went through all the plates on Todd's web site and I couldn't find the MPG image. It certainly looks like one of Todd's. Not sure what going on there.

Robert - If Jerry Fauske responds, please let us know. Thanks!

Moved tentatively to Pelochrista aemulana
Moved from Pelochrista.

det. Jerry Fauske, however matching image on MPG is actually described as Eucosma aemulana, but the images on BOLD look nothing like it. I'm leaving here until I can sort it out.

I updated the species page. This species is in Eucosma per Gilligan & Wright, 2013 (1). (To see the most recent updates for tortricids, you can always do a search at

I think there is a chance that Jerry Fauske made an error. Could you please ask him to confirm the ID? I also updated the species page with references and it does not seem likely that this is that species. Thanks!

Reason I tentatively posted ...
Jerry said "looks like Pelochrista aemulana," and it does look identical to Todd's on MPG, but looks nothing like the specimens on BOLD. I'm thinking it's probably best posted either Eucosma sp. or Pelochrista sp.. It's really confusing what has been transferred where.

BTW I messaged Jerry, but haven't heard back.

a variant agassizii?
This is the BOLD page for agassizii; the sample CNCLEP00105221 (the last one in the sequence) seems quite different from the other four samples, and closer to my individual. Ed Knudson has collected agassizii near this location in Texas:

aemulana on MPG - ??
Robert, you said: "Jerry said "looks like Pelochrista aemulana," and it does look identical to Todd's on MPG,"
- but this is the MPG page for E. aemulana - and it has no images... ? I am confused!:

Todd Gilligan's specimen
Plates of Eucosmini adults (1)

Todd's specimen
Thanks Robert - Todd's moth looks almost identical to mine; do we know where/when it was collected?
It does not look much like the specimens of agassizii on BOLD, and I don't think it can be the aemulana from the Old World, so what is it?

I guess I still don't know my way around MPG... If there is a specimen photo of 3026 E. aemulana (Todd's) on MPG, then why does it not appear in the page for 3026, E. aemulana - ?

I suspect ...
I suspect Todd's ID is not correct, which has lead to all the confusion. Eucosma has undergone a lot of changes in recent years, which are still undecided.


Moved from ID Request.

I agree that these "silver" Eucosmoas are very difficult and you will have to wait for Terry Harrison to weigh in, but considering how solid your silver lines are, did you consider BOLD this one, Hodges #3024 – Eucosma gilletteana? I realize that MPG does not show Texas in its range, but using the markings I think it is a contender for species.

I don't recognize
I've found a lot of white with brown markings, but nothing like this. I posted on facebook. maybe someone will know
