Habitat
Associated with containing its plants: woodlands, forest edges, and shrublands where dogwoods (Cornus), sumacs (Rhus), and blueberries (Vaccinium) occur.
Distribution
Eastern North America: Quebec, Canada; United States including Texas, Maine, Kentucky, Ohio, Illinois, and Michigan. GBIF records also indicate occurrences in Ontario, Florida, and Atlantic States.
Diet
feed on Rhus typhina (staghorn sumac), Cornus including Cornus asperifolia and Cornus drummondii (roughleaf dogwood and Drummond's dogwood), and Vaccinium species (blueberries). do not feed.
Host Associations
- Rhus typhina - larval staghorn sumac
- Cornus asperifolia - larval roughleaf dogwood
- Cornus drummondii - larval Drummond's dogwood
- Vaccinium - larval blueberries
Life Cycle
mine the leaves of plants, creating characteristic blotch mines or serpentine mines within leaf tissue. occurs within the mine or in a silken on the leaf surface. Multiple per year are likely given the extended period typical of Caloptilia in temperate regions.
Behavior
are and attracted to light. are internal feeders, mining between the upper and lower of leaves.
Ecological Role
As a , create feeding galleries that may affect photosynthetic capacity of plants, though typically not causing significant damage to healthy plants. The contributes to the complex of that leaf in woodland .
Human Relevance
Minor economic significance; may occasionally be noticed on ornamental dogwoods or blueberry plantings, but not considered a serious pest. The is documented through citizen science platforms including iNaturalist.
