Virbia  - Virbia aurantiaca

Virbia - Virbia aurantiaca
Henderson, Chester County, Tennessee, USA
May 20, 2011

Moved from Virbia fragilis.

Jen Zaspel agrees with aurantiaca for these three specimens.

According to the Virbia revision, "this species has been collected in open fields in the Black Hills, South Dakota and in Boulder, Colorado. The range extends north to Alberta and British Columbia, south to New Mexico," so TN would be way out of the known range. It also doesn't indicate that fragilis ever has a form with the solid black band on the hindwing like this. Are you sure these aren't just aurantiaca?

I'm not sure of anything sinc
I'm not sure of anything since I'm not the one that identified it. I know I sent this or maybe the other one I have on BG to Hugh so maybe he can shed some light on it.

I didn't question the ID because it was good match for the supposedly DNA confirmed one that Mark Dreiling has on MPG. I just checked and that one is now identified as aurantiaca.

I also noticed
I also noticed that the species description on the BugGuide page for ferruginosa was in fact copied and pasted from the Virbia revision, but from the Virbia *fergusoni* section, rather than ferruginosa (I guess someone misread the name). So there have been a lot of ferruginosa pictures misidentified on other species pages, presumably because they didn't match the description on the BugGuide page. I bet that's what happened with those North Dakota ones.

Got it
I'll check with Hugh about this one then. I also doubt the IDs on the eastern ND specimens, which look like ferruginosa to me, and are also much farther east than fragilis is known from. When Hugh and I compared Virbia specimens last fall, we seemed to be on the same page about IDing them, so I'll see if he agrees about these as well.
