Bucculatrix montana Braun (Figs. 60, 60a, 61.)
1920. Bucculatrix montana Braun, Ent. News XXXI: 77. Type $, Mountain Lake, Virginia [A.F.B.Coll.].
Head white, a few fuscous hairs in the tuft; antennal stalk pale fuscous. Thorax and fore wings white, the fore wings marked with ocherous, more or less fuscous dusted, or sometimes dark fuscous streaks ; from base of wing and lying above the fold, a more or less well defined basal streak (absent in the type) extends along the axis of the wing where in darker specimens it may join the apices of the three costal streaks ; three equally spaced oblique costal streaks, the first before middle of costa and bending below costa to join in the middle of the wing the second costal streak which runs into some fuscous dusting on the termen, and just before its tip is marked with a few fuscous scales; from termen just before apex a streak of blackish fuscous scales, in line with the axis of the wing, extends to the tip of the apical cilia; from beyond middle of dorsum, a curved streak bending back along fold is marked, especially on the fold, with fuscous dusting. Cilia whitish, except just below the apical fuscous line; a fine line of scattered dark-tipped scales in the terminal cilia meets the fuscous apical line at a very acute angle at about half its length. Hind wings pale fuscous, darker in males, especially in dark-marked specimens. Legs pale ocherous, hind tarsal segments tipped with fuscous, except in the palest specimens. Abdomen ocherous. fuscous above in the middle segments in females, entirely fuscous in males.
Alar expanse 10.5 to 13 mm.
Male genitalia (figs. 60, 60a). Harpes small, swollen at base, tapering to narrow cucullus bearing short blunt conical setae ; socii short setose, variable in length, somewhat enlarged distally and arising well before tip of tegumen ; aedeagus long, tapering to the slender apex. Scale sac large.
Female genitalia (fig. 61). Ostium narrowly sclerotized anteriorly, produced posteriorly ; signum as in solidaginiella.

Food plant and early stages unknown. The type specimen emerged from a cocoon typical of the genus ; cocoon reddish ocherous, with ten low ridges.
The distinguishing character of B. montana is the blackish streak extending in a line with the longitudinal axis of the wing from near apex of the wing to the tip of the apical cilia.

Bucculatrix montana is a moth in the family Bucculatricidae. It was described by Annette Frances Braun in 1920 and is found in North America, where it has been recorded from Ontario, Nova Scotia, Indiana, Maryland, Virginia, Ohio, Michigan, Maine, New York, New Jersey, Massachusetts and Georgia.

The wingspan is 10.5–13 mm. The forewings are white, marked with ocherous, more or less fuscous dusted, or sometimes with dark fuscous. The hindwings are pale fuscous. Adults are on wing from June to August.
