Cremastobombycia ignota
(Frey & Boll, 1873)
Cremastobombycia ignota is a small in the Gracillariidae, described by Frey & Boll in 1873. It is distributed across multiple regions of the United States, from the Atlantic coast to the Midwest and Texas. The is a leaf-miner, with larvae that feed internally within leaves of various Asteraceae plants.

Identification
Identified by its minute size (wingspan under 8 mm) and association with specific Asteraceae plants. Leaf mines on Elephantopus, Helianthus, Verbesina, or Ridania may indicate presence. Definitive identification requires examination of genitalia or , as Cremastobombycia species are morphologically similar.

Habitat
Occurs in areas where plants grow, including open woodlands, meadows, and disturbed supporting Asteraceae vegetation. Specific microhabitat preferences are not documented.
Distribution
United States: Illinois, Texas, Kentucky, Maine, New York, Massachusetts, Washington, and Ohio. Records span Atlantic coastal states, Midwest, and Pacific Northwest.
Diet
Larvae feed on leaves of Asteraceae: Elephantopus (including E. carolinianus), Helianthus species (including H. annuus and H. giganteus), Ridania alternifolia, and Verbesina species (including V. alternifolia and V. virginica). Feeding occurs as leaf miners within plant foliage.
Host Associations
- Elephantopus carolinianus - larval plant
- Helianthus annuus - larval plant
- Helianthus giganteus - larval plant
- Ridania alternifolia - larval plant
- Verbesina alternifolia - larval plant
- Verbesina virginica - larval plant
Life Cycle
Larvae are leaf miners, developing inside plant leaves. Complete details including number of per year and stage are not documented.
Behavior
Larvae create leaf mines in plant foliage. is not well documented.
Ecological Role
As a leaf-mining herbivore, larvae may influence leaf physiology and nutrient cycling in plants. Potential role in regulating Asteraceae or as prey for is not documented.
Human Relevance
No documented economic importance. Occasionally encountered by botanists and entomologists surveying leaf-mining insects on native Asteraceae.
