Originally named from mine and larvae in leaves of Rosa lucida, 
it mines leaves of various species of rose, but is particularly 
partial to the climbing wild rose, Rosa setigera. The mine (Fig. 
42) is ser])entine usually much contorted, frequently closely 
following the edge of the leaf in its early course, with a broad line 
of frass, and measuring at its end 1.5 to 2 mm. across. Larva 
green. Cocoon yellowish brown, much flattened. .Three gen- 
erations: full grown larvae in June and early July, in August and 
in October; mines containing larvae nia}', however, be found at 
almost any time during the summer and fall iq) to November. 
This species may be distinguished from N . slingerlandeUa by 
the darker head, dark cilia, and somewhat broader wings.

Tuft ochraceous; eye-caps whitish. Thorax and fore wings fuscous, faintly 
purple, with the scales before the fascia paler at their bases, so that this 
portion of the wing is somewhat irrorated and paler than that be 5 mnd the fascia 
where the wing is dark fuscous purple. The fascia is just beyond the middle, 
dull white, sometimes a little convex and broadening on the dorsum. Cilia 
graj’, pale gray around the apex. Hind wings gray. Legs shining gray, shaded 
with ocherous. Abdomen blackish above, yellowdsh beneath. 
Expanse . — 4 to 4.5 mm. 
Localities. — Pennsylvania (Clemens); Kentucky (Chambers); 
Ohio. 
The larvae mine leaves of various species of willow. The 
mine (Fig. 25) is a gradually broadening linear tract, sometimes 
straight, but often bent back on itself toward the end; occasion- 
ally (on Salix discolor) its latter portion is a more or less spiral 
l)lotch (Fig. 44). Cocoon ocherous or brownish. There are at 
least three generations a year; larvae may be collected from June 
until the end of October. 
In spite of the difference in appearance of the mine, I am forced 
to conclude that Ah discolorella is identical with Ak fuscotibiella, 
since it is impossible to separate the moths.
