1- Neomyia cornicina(Small False Greenbottle)
Neomyia is a of flies in the Muscidae, commonly known as False Greenbottles. The genus includes such as Neomyia cornicina, a dung fly that inhabits cattle and has been extensively studied as a non-target organism affected by veterinary pharmaceuticals in livestock waste. Species in this genus exhibit thermophilous and adapt their spatial and temporal distribution to climatic conditions.

Identification
Members of Neomyia may be distinguished from the superficially similar greenbottle flies (Lucilia, Calliphoridae) by their placement in Muscidae rather than Calliphoridae; the "False Greenbottles" reflects this resemblance. Specific diagnostic features for the are not documented in available sources.

Habitat
Associated with , particularly cattle dung; also recorded in Mediterranean oak forest .
Distribution
Recorded from the Iberian Peninsula; distribution records from GBIF include Denmark (DK), Norway (NO), Sweden (SE), and Vermont, United States.
Seasonality
activity with spatial and temporal distribution patterns adapted to climatic conditions throughout the year.
Diet
; larvae and feed on , particularly cattle dung.
Life Cycle
Larval development occurs in ; emerge from pupae and require feeding on dung for ovarian development.
Behavior
Exhibits thermophilous , adapting spatial and temporal distribution to climatic conditions. feed on moist ; rates correlate with feeding activity and ovarian development. Locomotory ability and activity levels are sensitive to pharmaceutical residues in dung.
Ecological Role
Member of insect fauna contributing to dung decomposition; reductions may impair dung breakdown.
Human Relevance
Used as a model organism in ecotoxicological studies assessing non-target effects of veterinary pharmaceuticals (synthetic , ivermectin, eprinomectin) in livestock . Sensitive to these compounds, showing reduced survival, , and body size.
