Cameraria aceriella
(Clemens, 1859)
maple leafblotch miner
Cameraria aceriella, the maple leafblotch miner, is a small in the Gracillariidae. It is a leaf-mining whose larvae create distinctive blotches on maple leaves. The species was first described by James Brackenridge Clemens in 1859 and is primarily found in northeastern North America.

Identification
The small size (7–9 mm wingspan) and association with Acer plants help distinguish this . The leaf mines produced by larvae appear as blotches on maple leaves, which may aid in detection. Definitive identification likely requires examination of genitalia or molecular analysis.
Appearance
have a wingspan of 7–9 mm. As a member of the Gracillariidae , it is a very small with narrow, pointed wings typical of microlepidoptera. Specific coloration details are not well documented in available sources.
Habitat
Found in areas where maple (Acer) grow, including deciduous forests and urban or suburban landscapes with maple trees.
Distribution
Eastern North America: Quebec and Ontario in Canada; Connecticut, Illinois, Kentucky, Maine, Maryland, Michigan, New York, Pennsylvania, Vermont, and Wisconsin in the United States.
Seasonality
are active from late May through June. Larval activity presumably occurs during the growing season when maple leaves are available.
Diet
Larvae feed on Acer , specifically documented on Acer rubrum (red maple) and Acer saccharinum (silver maple). They mine the leaves of their plant, creating internal feeding tunnels.
Host Associations
- Acer rubrum - larval red maple
- Acer saccharinum - larval silver maple
Life Cycle
Larvae are leaf miners that feed internally within maple leaves. The complete has not been fully documented in available sources.
Behavior
Larvae mine leaves, creating blotchy mines rather than linear serpentine patterns. are and attracted to light, as is typical for many small .
Ecological Role
As a , larvae may cause minor aesthetic damage to trees but are not considered significant defoliators. They serve as a food source for and other natural enemies.
Human Relevance
Minor aesthetic concern for ornamental maple trees due to leaf mining damage. Not considered an economically important pest.
