Asteromyia chrysothamni
Felt, 1918
Asteromyia chrysothamni is a gall midge in the Cecidomyiidae, described by Felt in 1918. The species is associated with Chrysothamnus, a of rabbitbrush shrubs in the Asteraceae family. Like other members of its genus, it induces gall formation on plants. The species has been documented through iNaturalist observations, though detailed biological studies remain limited.

Identification
Identification relies on association with galls on Chrysothamnus plants and morphological features typical of the Asteromyia, including reduced wing venation and characteristic antennal structure. Specific diagnostic features distinguishing it from congeneric require examination.
Habitat
Associated with supporting Chrysothamnus , which include dry, open areas in western North America such as sagebrush steppe, pinyon-juniper woodlands, and disturbed semi-arid sites.
Distribution
Western North America, corresponding to the range of its Chrysothamnus plants.
Host Associations
- Chrysothamnus - gall inducer of rabbitbrush shrubs; specific within the genus not documented in available sources
Ecological Role
As a gall inducer, modifies plant tissue structure, potentially affecting plant growth and providing microhabitats for other organisms.
