Caryomyia urnula

Distinguished from congeners by the urn-shaped gall it induces on Carya foliage. Specific morphological characters for adult identification require examination of male genitalia and antennal flagellomeres, as is standard for Cecidomyiidae taxonomy. Differential diagnosis from other Caryomyia species relies on gall morphology and host association.

Associated with deciduous forests and woodlands containing hickory or pecan trees (Carya spp.), the host plants for gall induction.

Known from the eastern United States where Carya species occur; specific locality data for type specimens and additional records are sparse in accessible literature.

Adult emergence and gall formation occur during the growing season of host Carya trees; precise phenology undocumented.

• Carya - gall inductionHost plant for gall formation; specific Carya species unconfirmed

Induces gall formation on host plant leaves; complete life cycle details including larval development and overwintering strategy are not documented.

Larval stage induces characteristic urn-shaped galls on host foliage. Adult behavior unrecorded.

As a gall inducer, modifies host plant tissue and creates microhabitat for potential inquilines and parasitoids within the gall structure.

No documented economic or medical significance; of potential interest to forest entomologists and gall researchers.
