Leaf Blotch Miner Moth - Phyllonorycter clemensella

Leaf Blotch Miner Moth - Phyllonorycter clemensella
Chanhassen, Carver County, Minnesota, USA
July 16, 2008
Size: 3.9 mm long
This is a Phyllonorycter and, in comparison to the MPG pinned plate, it looks like Phyllonorycter lucidicostella. I'd love other opinions as I can't find a live specimen photo to compare.

Nice Image!
Markings on the rear part of wing suggest to me the front part of a long legged centipede. Probably just a coincidence.

Moved from Phyllonorycter.

Bob Patterson tells me this is Hodges #744.

Phyllonorycter clemensella
I agree that this moth is closest to P. lucidicostella, among the species illustrated on microleps and MPG. In actuality, it is a spot-on match for a species that is not yet illustrated on the two Web guides just mentioned, that being P. clemensella, which, just as does P. lucidicostella, feeds on sugar maple, Acer saccharum (Aceraceae). When I rear Phyllonorycter from that host in Illinois, I get P. lucidicostella more often than P. clemensella, but I get the latter species often enough that I don't consider it rare; and Braun in her 1908 revision (Trans. Am. Ent. Soc. 34: 280) characterized it as common at Cincinnati, Ohio. I just haven't happened to rear one since I began taking photos for the Web. So it is great, now, to have your superb image of this species online for reference. Diagnosis: note that in P. lucidicostella, there is a subcostal line of the ochreous color that dominates the apical part of the wing; and that this line runs from at or near the base of the wing, out to a point where it runs into a line of the same color (with no discernible black in it), that starts along the costa and then angles posterad. In P. clemensella (as in the moth in your photo), there is no subcostal ochreous line (basal part of wing entirely white), and the angled line is largely black, rather than entirely ochreous. Hope this helps.
