Leaf mine in rose: possibly Stigmella rosaefoliella? - Stigmella

Leaf mine in rose: possibly Stigmella rosaefoliella? - Stigmella
Carpinteria, Santa Barbara County, California, USA
December 26, 2011
Size: leaf is ~5cm long
I was enjoying Chapter 10 (Leaf Mines) in Tracks and Signs of Insects and Other Invertebrates, and wondered if I had any leaf mines in my front yard. About 30 seconds later I was excited to find several in my wife's roses (she, somewhat less-so, but she was gracious enough to take a look when I shared the discovery with her). From the description in the book it sounds like this might be the work of Stigmella rosaefoliella; it also looks like a pretty good match for the description and image at the species' Wikipedia article. Thoughts?

See guide page. Erik said your mine looks like S. centifoliella, but the mines of these two introduced species can be difficult to distinguish.

Nice! I was going to caution that western species are poorly known and that Wilkinson & Newton* don't mention any western records for this species, but curiously the only point on the MPG map for this species is in California, so I don't see any reason to doubt the ID.

I tried to raise one of these this summer but it was parasitized:
