1496  Fernald's Cosmopterix Moth ?? - Cosmopterix

1496 Fernald's Cosmopterix Moth ?? - Cosmopterix
Bartlesville, Washington County, Oklahoma, USA
May 30, 2010
My best match is 1496 – Cosmopterix fernaldella – Fernald's Cosmopterix Moth from MPG
Found at UV light near pond in wooded area of a flood plain.

Apex antenna color?
What color were the apex of the antennae? If they were brown, this is probably C. scirpicola. If black, then C. facunda. C. facunda is known from one specimen in Texas so C. scirpicola is more likely.

 
Dissection Required
BOLD:AAD1169, the BIN group for scirpicola with 4 samples, includes specimens of fernaldella, also with 4. It may be that the scirpicola specimens are misidentified. I would not trust BOLD's identification here.

The BIN in which Mark's example is placed has two other examples, one of which, sample BIOUG01418-D04 from FL, shows the antennae fairly clearly. The apical 3 segments are dark brown followed by 1 white, 5 brown, 1 white, then brown for the rest. Hodges (1962) described scirpicola here from specimens collected in Oklahoma City. The antennae have "... apical nine segments olive-brown, preceded by one white, then brown segments (or apical three brown, one white, five brown, one white, then brown)." But this is the same pattern for fernaldella with ebriola also being very similar. Hodges separates this species from those by dissection.

Edit - Koster (2010) notes that fernaldella, ebriola, and scirpicola cannot be separated without dissection. (1)

 
Range seems to be helpful in sorting out these three
I've been primarily using range to sort these to species.

Here are states/provinces Koster mentions records of each species:

scirpicola: South Carolina, Alabama, Oklahoma, Florida, Louisiana, California, and eastern Wyoming.

fernaldella: Quebec, Washington, Ontario, British Columbia, Michigan, Wisconsin, Maine, and Minnesota

ebriola: North and central Florida, South Carolina, southern Mississippi.

It appears that everything up north can be safely called fernaldella. It gets a little trickier in the deep south.

 
Cosmopterix nr. ebriola
This is very close to the BIN with ebriola from Florida and I think it may be an undescribed species.

 
I do not know the colors.
The specimen is shown at BOLD:AAY6961
It is about 6% off of C. scirpicola. C. facunda is not in BOLD

Moved
Moved from Fernald's Cosmopterix Moth.
The DNA results are in and it does not match Cosmopterix fernaldella
BOLD LPOKD946-10

Looks like MPG agrees. Your image appear on the species page here.
