Phyllonorycter fragilella
(Frey & Boll, 1878)
Phyllonorycter fragilella is a small leaf-mining in the Gracillariidae, with a wingspan of 8.5–9 mm. The is known from eastern Canada and the north-central and northeastern United States. Larvae feed on honeysuckles (Lonicera), snowberries (Symphoricarpos), and milkberry (Chiococca alba), creating mines within plant leaves.

Identification
Distinguished from other Phyllonorycter by association with specific plants (Lonicera, Symphoricarpos, Chiococca) and geographic distribution. are extremely small (8.5–9 mm wingspan) and require microscopic examination or genitalia dissection for definitive species-level identification. The leaf mines of larvae may show species-specific characteristics, though these are not well documented in available literature.
Images
Appearance
Small with wingspan 8.5–9 mm. As a member of the Phyllonorycter, likely exhibit the characteristic forewing pattern of alternating light and dark bands or spots typical of leaf blotch miner moths, though specific markings for this are not detailed in available sources.
Habitat
Associated with supporting its plants: Lonicera (including cultivated and native honeysuckles), Symphoricarpos species (coralberry, snowberry), and Chiococca alba (milkberry). These include woodland edges, shrublands, and areas with ornamental plantings.
Distribution
Eastern North America: Canada (Québec, Ontario, British Columbia); United States (Texas, Maine, Michigan, New York, Massachusetts, Illinois, Wyoming).
Diet
Larvae feed on Lonicera sempervirens, Lonicera × bella, Symphoricarpos orbiculatus, Symphoricarpos vulgaris, and Chiococca alba. They mine the leaves of their plants, feeding internally between the leaf surfaces.
Host Associations
- Lonicera sempervirens - larval trumpet honeysuckle
- Lonicera × bella - larval Bell's honeysuckle, a hybrid
- Symphoricarpos orbiculatus - larval coralberry
- Symphoricarpos vulgaris - larval snowberry
- Chiococca alba - larval milkberry
Life Cycle
Complete with leaf-mining larval stage. Larvae feed internally within leaves of plants, creating blotch or tentiform mines typical of the . Specific details of site, number of per year, and stage are not documented in available sources.
Behavior
are and have been observed at blacklight. Larvae are endophagous leaf miners, feeding between the upper and lower of plant leaves.
Ecological Role
As a , larvae may influence plant physiology by reducing photosynthetic capacity of mined leaves. The contributes to the diverse of specialized herbivores associated with Caprifoliaceae (honeysuckle ) plants.
Human Relevance
Minor potential significance in horticulture due to larval feeding on ornamental Lonicera and Symphoricarpos . No major economic impact documented.
Similar Taxa
- Other Phyllonorycter speciesMany are morphologically similar and require dissection or plant association for identification. P. fragilella is distinguished by its specific host plant relationships with Lonicera, Symphoricarpos, and Chiococca.
- Other Gracillariidae leaf minersLeaf mining habit is shared across ; Phyllonorycter typically create blotch mines on woody plants, while other may create linear mines or feed on herbaceous plants.
