Phyllocnistis on-eubotrys-racemosa
A tiny leaf-mining in the Gracillariidae, Phyllocnistis on-eubotrys-racemosa is part of the 'microlepidoptera'—a group of moths typically measuring less than 10 mm. Like other members of its , this likely produces larvae that mine between leaf layers, creating distinctive serpentine or blotch mines. The species epithet suggests an association with the plant genus Eubotrys (fetterbush), indicating a specialized relationship.

Identification
Requires dissection of genitalia for definitive identification, a common constraint for Phyllocnistis . Lance-shaped wings with long fringing that give a feather-like appearance. Some Phyllocnistis species exhibit reflective or metallic scaling. The specific epithet 'on-eubotrys-racemosa' implies association with Eubotrys racemosus (fetterbush), which may aid in field recognition where this occurs.
Habitat
Associated with Eubotrys racemosus (fetterbush), a wetland shrub in the heath (Ericaceae). Likely occurs in moist woodland edges, swamps, and bog margins where this plant grows.
Distribution
Distribution poorly documented; likely restricted to regions where plant Eubotrys racemosus occurs in eastern North America. Citizen science records from blacklight sampling suggest it may be underreported due to its minute size.
Host Associations
- Eubotrys racemosus - larval Specific epithet indicates this association; larvae mine leaves of this fetterbush
Life Cycle
Larvae are leaf miners, feeding between epidermal layers of leaves. likely occurs within the mine or in a silken cocoon on the leaf surface, as in related Phyllocnistis . are and attracted to ultraviolet light.
Behavior
attracted to blacklights/ultraviolet light sources. Larvae create serpentine or blotch mines in leaves, remaining concealed between tissue layers.
Ecological Role
; herbivore that consumes photosynthetic tissue of plant. Serves as potential prey for and other natural enemies.
