Scoparia basalis ?? - Eudonia commortalis

Scoparia basalis ?? - Eudonia commortalis
McLean Mill Historic Site, Alberni Valley, Vancouver Island, British Columbia, Canada
July 3, 2009
ID based primarily on similarity to Dick Wilson's photo:

for the help on this one.

When I first posted it back in 2009, the BC list at the time ("Lepidoptera Families & Associated Orders of BC" Scudder & Cannings 2007) included Scoparia basalis.

Have just checked the new list which came out in 2015 ("Checklist of the Lepidoptera of BC", Pohl et al). S. basalis has been changed to unconfirmed with the following note: "Western records are unconfirmed and may refer to S. biplagialis."

Tentative ID
I should have added that it is tentative. I don't think you were suggesting that S. biplagialis should be considered but if so, I think the pm. line is different.

FYI - Pohl et al. (2015) is superseded by the new Canada and Alaska checklist, Pohl et al. (2018)(1). PDF is available for download.

Moved from Scoparia.

Eudonia commortalis
The comparatively straight costa and the claviform nearly separted from the am. line I think would exclude Scoparia basalis. I think Eudonia heterosalis is eliminated by the lack of a sharply angled pm. line. I think there may be more than one species involved in what we call Eudonia commortalis.

Edit - There is more than one species involved with Eudonia commortalis at BOLD but I don't think any refer to commortalis except for BOLD:AAC7964 which this seems to match.


Scoparia basalis???
This species is not known to occur west of Ontario.
