Eiseman & Lonsdale, 2018
Calycomyza avira is a of leaf-mining fly in the Agromyzidae, described from North America in 2018. Like other members of its , it likely produces serpentine or blotch mines in living leaf tissue. The species was established based on morphological distinctions from and associated plant records. It represents part of a diverse radiation of Calycomyza species specialized on Asteraceae hosts.

Identification
Diagnostic features include male genitalic structures, particularly the distiphallus shape and surstylus , which distinguish it from the similar C. ambrosiae and C. platyptera. The exhibits reduced wing markings compared to some . Identification requires microscopic examination of terminalia; external characters alone are insufficient for reliable determination.
Distribution
Known from eastern North America, with records from the northeastern United States. The type series was collected in association with its plant in mesic deciduous forest understory.
Host Associations
- Solidago - larval Known to mine leaves of goldenrod (Asteraceae)
Ecological Role
As a , larvae create endophytic feeding tunnels that damage photosynthetic tissue. This represents a specialized herbivore role within plant-insect , with potential impacts on plant .
