Astrotischeria ambrosiaeella
(Chambers, 1875)
Astrotischeria ambrosiaeella is a small in the Tischeriidae, first described in 1875. The is known for its leaf-mining larvae that feed on giant ragweed (Ambrosia trifida). It occurs across a broad geographic range in North America, from California to the southeastern United States.

Identification
Members of Tischeriidae are small with distinctive wing venation and often metallic markings. This can be distinguished from other Astrotischeria by association with its plant Ambrosia trifida and by geographic distribution overlapping with that host's range. likely resemble other tischeriids with narrow, wings and relatively simple patterning.
Habitat
Associated with stands of giant ragweed (Ambrosia trifida), typically in disturbed, open including agricultural fields, roadsides, and riparian areas where this plant grows.
Distribution
Documented from California, Florida, Louisiana, Ohio, and Texas. The distribution corresponds to the range of its plant Ambrosia trifida in North America.
Diet
Larvae feed exclusively on Ambrosia trifida (giant ragweed), mining the leaves. feeding habits are not documented.
Host Associations
- Ambrosia trifida - larval Leaves are mined by larvae
Life Cycle
Larvae are leaf miners, creating mines in the leaves of Ambrosia trifida. Details of , timing, and number of per year are not documented.
Behavior
Larvae construct blotch or serpentine mines in leaves of the plant. Mining is the primary documented habit.
Ecological Role
As a herbivore on giant ragweed, this contributes to natural of a significant agricultural and weed. The leaf mining damage may reduce photosynthetic capacity of plants.
Human Relevance
Potential value as a agent for giant ragweed, a problematic weed in agriculture and a source of allergenic pollen. No documented negative impacts to human activities.
Similar Taxa
- Other Astrotischeria speciesMany Tischeriidae are morphologically similar; reliable identification often requires association with specific plants or dissection of genitalia.
- Other leaf-mining moths on AmbrosiaSeveral contain that mine Ambrosia leaves; mine shape and larval distinguish Tischeriidae from agromyzid flies and other miners.
