Species Guides
1Chilophaga is a of gall midges (Diptera: Cecidomyiidae) established by Gagné in 1969. The genus includes whose larvae develop in plant tissues, with Chilophaga virgati documented feeding on switchgrass inflorescences in the northern Great Plains. Members serve as for in the Platygastridae.

Identification
As a of Cecidomyiidae, Chilophaga are small, delicate flies with reduced wing venation typical of gall midges. Species-level identification requires examination of male genitalia and larval gall characteristics. Chilophaga virgati is associated with switchgrass inflorescences, which may aid in field recognition.
Habitat
Associated with grassland , specifically the basal meristematic tissues of grass inflorescences. Chilophaga virgati has been collected from switchgrass (Panicum virgatum) in eastern South Dakota.
Distribution
Documented from eastern South Dakota in the northern Great Plains of North America. Distribution of other within the is not well documented.
Diet
Larvae feed on basal meristematic tissues of grass inflorescences. Chilophaga virgati specifically feeds on Panicum virgatum.
Host Associations
- Panicum virgatum - plantlarvae feed on basal meristematic tissues of the inflorescence
Life Cycle
Larval stage develops within plant tissue. occurs within the plant or nearby substrate. Serves as host for the Platygaster chilophagae, with cocoon clusters of 4–14 pupae emerging from each host larva.
Ecological Role
Gall-former or in grass inflorescences. Acts as for , supporting higher in grassland .
Similar Taxa
- Other Cecidomyiidae generaMany gall midge are morphologically similar and require genitalic dissection for definitive identification; plant association provides a useful field character for Chilophaga virgati
