Identification
are small with reduced wing venation characteristic of Tischeriidae. Larval mines are recognizable as linear to blotch-shaped patterns on leaves of Heliopsis helianthoides and Ambrosia trifida. Specific adult diagnostic features are not well documented in available sources.
Habitat
Associated with open supporting its plants, including prairies, meadows, and disturbed areas where Heliopsis helianthoides (oxeye sunflower) and Ambrosia trifida (giant ragweed) occur.
Distribution
Recorded from Illinois, Missouri, and Ohio in the central United States.
Diet
Larvae feed on leaves of Heliopsis helianthoides and Ambrosia trifida, creating internal leaf mines. feeding habits are not documented.
Host Associations
- Heliopsis helianthoides - larval leaf mining
- Ambrosia trifida - larval leaf mining
Life Cycle
Larval development occurs within leaf mines. Specific details regarding , timing, and number of per year are not documented.
Behavior
Larvae are leaf miners, feeding internally between leaf surfaces. No other behavioral observations are recorded.
Ecological Role
As a , larvae may influence leaf physiology of plants. Specific ecological impacts have not been studied.
