Astrotischeria helianthi
(Frey & Boll, 1878)
Astrotischeria helianthi is a small in the Tischeriidae, described by Frey and Boll in 1878. The is native to North America and has been recorded in Missouri and Ohio. Tischeriid moths are leaf-miners, and the specific epithet 'helianthi' suggests a potential association with plants in the sunflower family (Asteraceae).

Taxonomic Note
The Astrotischeria was established for New World previously placed in Tischeria. The specific epithet 'helianthi' was assigned by Frey and Boll in 1878, predating the use of the same epithet for the fruit fly Acanthiophilus helianthi, a safflower pest in Europe and Asia. These are unrelated species in different orders.
