This moth was traveling from one Himalayan blackberry leaf to the next. It would land on the edge of the leaf, then curl its tail under the edge of the leaf. I believe it was depositing eggs - which you can hopefully see in the third image. The egg appears red. About five minutes after this one wandered off, a second smaller one appeared (approx 3/4 inch), mimicking what the first one did. Before today, I'd never seen the moth.

I found images of two moths in your collection that look vaguely similar to this one, but none that came close to a match - specifically: the yellow fuzzy tail, the brown (double?) tuft of fur/hair atop the abdomen just behind the wings and the yellow pattern on the back of the thorax.

Any help in identifying this handsome little creature would be greatly appreciated.
