Drasteria? - Drasteria graphica

Drasteria? - Drasteria graphica
Spiderweb, Aiken County, South Carolina, USA
April 17, 2010
Attracted to light. This is the only image I have of this moth.

The only moths with an AM line shaped like this, that I have found, are Hodges#8619 Occult Drasteria Moth - Drasteria occulta and Graphic Moth - Hodges#8618 Drasteria graphica.

The South Carolina Moths Checklist only lists Hodges#08641 Drasteria grandirena as having been found in South Carolina.

Is this D. occulta or ???

Drasteria graphica
I think it is Drasteria graphica. Specimen is worn but I can see traces of the subterminal line. In D.occulta the subterminal line is absent. Are there sandy places in your area? Drasteria graphica is associated with sandy habitats.

 
My location...
is on the western edge of the Sandhills region of South Carolina.

The sand here is at least 350 ft deep, that's how deep our well is and except for a 40 ft deep layer of a chalky clay all they brought up was sand.

One reservation I had with D. graphica is it's only known host plant is Hudsonia tomentosa (Woolly Beach Heather) which apparently doesn't grow in South Carolina.

I saw a reference to D. occulta using blueberries as a host plant, which is more likely to be found in this area.

 
You should take in considerat
You should take in consideration that distribution maps on the website that you referred to don't represent complete distribution of a certain species, but only known herbarium data, literature data and confirmed observations. Another species of Hudsonia, Hudsonia ericoides, is also known as a food plant for D. graphica and this species has been recorded from SC (about 45 mi East from your location). Also both Hudsonia tomentosa and Hudsonia ericoides are associated with sandy habitats. They could be found in places with open sand. Do you know how does Hudsonia plant look like?
