Cerodontha angulata
(Loew, 1869)
Cerodontha angulata is a of fly in the Agromyzidae. The Cerodontha is part of a diverse group of small flies whose larvae develop within the tissues of grasses, sedges, and rushes, creating distinctive feeding tunnels between leaf layers. The species has been recorded across a broad geographic range including North America, South America, and Europe.

Identification
Cerodontha angulata belongs to a of small, slender flies typically under 5 mm in length. -level identification within Cerodontha generally requires examination of male genitalia and detailed study of wing venation patterns. The specific epithet "angulata" likely refers to angular features of the body or wing structure, though this requires verification from original description.
Habitat
Larvae develop in grasses, sedges, and rushes. are associated with grassy and wetland vegetation where larval plants occur.
Distribution
Recorded from United States, Canada, Guyana, Brazil, and Europe (Denmark, Norway, Sweden). The broad trans-Atlantic distribution pattern suggests either a naturally widespread or potential cryptic requiring further study.
Diet
Larvae are leaf miners that feed internally within grass blades and leaves of sedges and rushes, boring between the epidermal layers. Specific plant records for this are not documented in available sources.
Host Associations
- grasses - larval larvae mine within leaf blades
- sedges - larval larvae mine within leaves
- rushes - larval larvae mine within leaves
Life Cycle
Complete with , larva, pupa, and stages. Larvae develop as leaf miners within plant foliage. likely occurs within the mine or in soil. Specific timing and duration of developmental stages are not documented.
Behavior
are small, inconspicuous flies. Larvae are endophagous, feeding internally within leaf tissues and creating serpentine or blotch mines visible as pale trails on leaf surfaces.
Ecological Role
As leaf miners, larvae function as primary consumers of graminoid vegetation. Their feeding damage is typically minor and not economically significant. The contributes to nutrient cycling through herbivory and serves as potential prey for and other natural enemies.
Human Relevance
Not known to be of economic importance. The Agromyzidae contains some significant agricultural pests, but Cerodontha are generally associated with non-cultivated grasses and sedges.
Similar Taxa
- other Cerodontha speciesMany Cerodontha are morphologically similar and require genitalia examination for definitive identification. C. angulata is distinguished by specific male genitalic and wing characters described by Loew.
- Phytomyza speciesAnother large of Agromyzidae with leaf-mining larvae; distinguished by wing venation details and larval mine patterns.

Taxonomic note
The original description by Loew (1869) established this , but detailed modern redescriptions are lacking. The broad geographic distribution suggests need for molecular study to confirm conspecificity across .
