Identification
Extremely small size (6–7.5 mm wingspan) distinguishes this from larger . Within Bucculatrix, identification to level requires examination of genitalia or association with plant and geographic location. The species is externally similar to other small Bucculatrix species; definitive identification relies on dissection or .
Appearance
Wingspan 6–7.5 mm. A minute with narrow, pointed wings typical of the . are likely dull-colored, consistent with other Bucculatrix , though specific coloration is not documented in available sources.
Habitat
Associated with bur oak (Quercus macrocarpa) stands. Found in deciduous forest and woodland where this oak occurs, including urban and suburban areas with mature oak trees.
Distribution
Eastern North America. Recorded from Ontario, Maine, New Hampshire, Massachusetts, Missouri, New Jersey, Washington D.C., North Carolina, and South Carolina.
Seasonality
on wing from August to October.
Diet
Larvae feed on Quercus macrocarpa (bur oak). They mine the leaves of this plant. feeding habits are not documented.
Host Associations
- Quercus macrocarpa - larval plant
Life Cycle
Larval stage mines leaves of Quercus macrocarpa. occurs in a ribbed cocoon, characteristic of the . emerge in late summer and autumn. Specific details of placement, larval instars, and stage are not documented.
Behavior
Larvae create linear or blotch mines in oak leaves. are and attracted to light.
Ecological Role
As a , larvae contribute to nutrient cycling in oak . levels are generally low enough that significant damage to trees is unlikely.
Human Relevance
No significant economic or ecological impact documented. Occasionally encountered by lepidopterists and naturalists during autumn surveys.
