"Desmia funeralis and D. maculalis (crambid moths) are common with extensive range overlap in North America - cannot be told apart by image without a ventral view-CV has suggested D. funeralis almost exclusively. There remain probably several 100s incorrectly IDed to species. "

Sounds like more should be IDed at genus and marked as community cannot improve in the Data Quality Assessment section?

Ok, I will review some of these when I have time. I figured that was the case, but don't believe that I had previously reviewed any that were already marked as research grade.

Posted by smoorman over 4 years ago

Yes, that could work if enough iNatters reversed a research grade that have several "agrees".

Needs a lot of time. I just spent 2 hours going over 120 or so mis-IDed Texas Desmia: add an ID, paste an explanation, wait for the spinning ball to take, respond to questions. Haven't started ones just IDed to genus.

If anyone wants to use my explanation: D. funeralis and maculalis can't be told apart without a ventral (underside) view

I have gone through a couple of pages for the eastern US and will do more when I get a chance. I think that many have already been reviewed because there was only 13 pages. When I finish, I will work on ones that need ID's as I have time. I'm sure that I will be getting a lot of comments. Lol.

agree! have found someone who seemed to agree with all dorsal-view-only misidentified Desmia spp. so I did spend a lot of time to correct them. Can't mark just Desmia as "this as far as ID can go" though, if there's already 2 incorrect IDs attached.

@joannerusso, I believe that you can mark it as "no, it's as good as it can be" if there are only two ID's that go to species as it will go back to just the genus once you ID only to genus. If there are three or more though some will have to withdraw their ID's to bring it back to just the genus.

Question: There is now a Grape Leaffolder and Leafroller Complex (Complex Desmia funeralis).
If an observation has been left at Desmia sp, without going down to species, is there any point in suggesting the Complex? I have been as I feel it provides a more defined ID but maybe I'm wasting my time?

I think that it would be a good thing to do.

Posted by smoorman over 3 years ago

"Pseudo-complex" (really a No Taxon either-or) would be fine, BUT only if you know how to definitively exclude Desmia subdivisalis (not uncommon across the southern US up the Atlantic Coast to at least MD), and the several other Desmia species in Florida. If those others can't be IDed to species (too worn, not correct pattern) they need to stay at the genus level.

I've already had to pluck out some placed in the complex that were not one of the two species included. "Good things" come with a price, and that price is familiarizing yourself with ALL the Desmia species, especially D. subdivisalis, before sticking an obs in the "complex".

If you stick with northern US you should be fine with using the D. funeralis-maculalis.

Thanks to you both for your feedback. Fortunately, I have the Identify page set for observations in my province, Ontario. For now, I'll focus on IDs down to species that lack a ventral view. Those will take a while anyway as I'm moving slowly trying to be sure with each observation.

Posted by teawren over 3 years ago

@teawren I'm so sorry not to have included Canada along with the northern US. My bad!

Posted by krancmm over 3 years ago

@krancmm Absolutely no need to apologize. When you mentioned southern species, my heart fell as I thought I might have screwed everything up. Thankfully, I learned today that when you have your overall Identify page set to a location, it applies that location to a link like that provided at the top of this flag. It was a great relief to learn that I'd been looking at just the Ontario observations. No wonder so many of the observer names were familiar to me. Thanks for your help with this.

No curation issue.
