Bucculatrix agnella
Clemens, 1860
Bucculatrix agnella is a of minute in the Bucculatricidae, first described by James Brackenridge Clemens in 1860. The species is known from scattered records across eastern and central North America, with a wingspan of approximately 7 mm. Like other members of its , it is commonly referred to as a 'ribbed cocoon-maker moth' due to the distinctive ribbed structure of its larval cocoon.

Identification
The Bucculatrix is distinguished from other microlepidoptera by the combination of narrow, forewings with distinctive venation and the ribbed cocoon produced by larvae. -level identification within Bucculatrix typically requires examination of genitalia or detailed wing pattern analysis. B. agnella may be distinguished from by subtle differences in forewing pattern and genitalic structure, though specific diagnostic features for this species are not well documented in accessible literature.
Appearance
are extremely small with a wingspan of about 7 mm. Detailed morphological descriptions of this are limited in available sources.
Habitat
Specific associations for B. agnella are not documented. Related Bucculatrix are generally associated with woody vegetation, particularly oaks and other trees.
Distribution
Recorded from multiple states in eastern and central North America: Pennsylvania, New Jersey, New York, Washington D.C., Massachusetts, Indiana, Tennessee, Kentucky, Michigan, Missouri, South Dakota, Maine, Ohio, and Texas. The appears to have a broad but patchy distribution across this range.
Life Cycle
Larvae of Bucculatrix typically construct distinctive ribbed cocoons on leaves or bark, from which the 'ribbed cocoon-maker moth' derives. Specific details of the for B. agnella are not documented.
Ecological Role
As with other small , likely serve as prey for insectivorous birds, bats, and other . Larval is unknown but related are leaf miners or skeletonizers.
Human Relevance
No documented economic or cultural significance. The has been recorded in citizen science observations during bioblitz events such as the City Nature Challenge.
Similar Taxa

- Other Gracillarioidea microlepidopteraSimilar minute size and narrow wings; Bucculatrix is distinguished by the ribbed larval cocoon and specific wing venation patterns.
