Longtail Skipper - Chioides albofasciatus

Longtail Skipper - Chioides albofasciatus
Austin, Travis County, Texas, USA
August 1, 2007
Because of the well-defined white stripe, I assume this is the White-striped Longtail, Chioides albofasciatus. (In the field guide I use, Brock and Kaufman's Butterflies of North America, this latin name given to this species is C. catillus, which I assume is just a synonym).

Mine looks quite different from the only image in the guide, though:

Is it the same species?

Same species
Yes, they are the same species. It just depends on the picture and lighting.

 
Thanks for the confirmation
What can explain the yellow spots on the forewing below, shown in my image? They are not like that in the other image, nor in my field guide. Is this just a variation, or maybe a gender related difference? Could it just be the sunlight shining through the wings? It was very sunny when I shot these.

 
Similar to what Ethan Said
Very cool tails. For color appearance differences: In some of the books and the photo you reference there may have been flash used where the light was coming from the camera. With your shots they were backlit so the colors show through the wing and appear brighter than they would without the backlight.

Any butterfly that is backlit will show colors through the wing that you wouldn't see otherwise. I saw some Melissa Blues and when I shot from above while the sun was setting, I could see the bottom spots and colors over the bright blue of the upper wing.

Your photos are very similar to the Silver Spotted Skipper on top. If backlit they really seem like bright spots. But without the backlighting they look like glassy dull spots. Lighting makes all the difference for some.

 
Ah
That makes great sense to me. If flash was used in the other photo, it would also explain why that specimen seems so much lighter.
