Phyllonorycter trinotella
(Braun, 1908)
Red Maple Blotchminer
Phyllonorycter trinotella is a micro- in the Gracillariidae, commonly known as the Red Maple Blotchminer. The has a wingspan of approximately 5 mm. Larvae are leaf miners that feed on several Acer species, creating blotch mines on the leaves. The species is known from eastern Canada and the northeastern and midwestern United States.

Identification
Extremely small size (5 mm wingspan) distinguishes this from most larger Lepidoptera. Within Phyllonorycter, identification requires examination of genitalia or detailed wing pattern analysis; the specific epithet 'trinotella' suggests three notable spots or markings. The association with Acer species may aid in identification where sympatric with other Phyllonorycter species on different hosts.

Appearance
Very small with a wingspan of about 5 mm. As a member of Phyllonorycter, likely have narrow, wings with distinctive patterning typical of the , though specific markings for this are not well documented in the provided sources.
Distribution
Québec, Canada; and United States: New Jersey, Maine, Connecticut, Ohio, Vermont, and Michigan. Additional records from Nova Scotia and Ontario, Canada per GBIF.
Diet
Larvae feed on Acer platanoides (Norway maple), Acer rubrum (red maple), and Acer saccharinum (silver maple). They mine the leaves of their plant, creating blotch mines.
Host Associations
- Acer platanoides - larval Norway maple
- Acer rubrum - larval red maple
- Acer saccharinum - larval silver maple
Life Cycle
Leaf-mining larvae feed within plant leaves. Specific details of and timing are not documented in available sources.
Behavior
have been observed at blacklight, indicating activity. Larvae are endophagous leaf miners.
Ecological Role
As a , larvae create blotch mines on maple leaves. The ecological impact on trees is likely minor given the small size of the insect and typical abundance patterns of Phyllonorycter .
Human Relevance
Not known to be of significant economic or ornamental concern. The 'Red Maple Blotchminer' reflects its association with a common native and ornamental tree .
