Phyllonorycter comptoniella
(Darlington, 1949)
Phyllonorycter comptoniella is a micro- in the Gracillariidae. The is known from a limited distribution in eastern North America, with records from southeastern Canada and the northeastern United States. Larvae are associated with sweetfern (Comptonia peregrina), and likely mine the leaves of this plant. are small and nondescript, typical of the .

Identification
Small , approximately 5-7 mm in wingspan, with the characteristic features of Phyllonorycter: narrow, forewings with distinct patterning of white and dark markings. Specific identification requires examination of genitalia or molecular analysis. Similar to other Phyllonorycter but associated with the distinctive plant Comptonia peregrina in its known range. Distinguished from congeneric leaf miners by host specificity and geographic distribution.
Habitat
Associated with supporting sweetfern (Comptonia peregrina), which occurs in dry, sandy, or rocky soils in open woodlands, forest edges, and disturbed areas. The plant is native to eastern North America and favors acidic, nutrient-poor substrates.
Distribution
Canada: Nova Scotia, Québec, Ontario. United States: Connecticut, New Jersey, Vermont. The has a restricted northeastern North American distribution coinciding with the range of its plant.
Diet
Larvae feed on Comptonia peregrina (sweetfern). The specific feeding mode is probable leaf mining, though this has not been definitively confirmed.
Host Associations
- Comptonia peregrina - larval sweetfern
Ecological Role
As a probable , larvae may influence leaf physiology of the plant and serve as prey for and other natural enemies. The contributes to the specialized herbivore fauna associated with sweetfern.
Similar Taxa
- Other Phyllonorycter speciesMany congeneric are morphologically similar and require dissection or analysis for reliable identification. plant association and geographic range provide the most practical distinguishing characters.
