Caryomyia striolata

Distinguished from other Caryomyia species by gall morphology and host association; adults are minute, delicate flies with reduced wing venation characteristic of Cecidomyiidae. Specific diagnostic features require examination of male genitalia and larval gall structure.

Associated with forests and woodlands containing Carya (hickory/pecan) host trees.

Known from North America; exact range limited by host tree distribution and collection records.

Adult emergence timed with host tree phenology; likely active during spring and early summer when new Carya foliage is available for gall induction.

• Carya - gall inducerGenus of hickory and pecan trees; specific host species for C. striolata not definitively established

Holometabolous; larvae develop within leaf galls on Carya, pupation occurs in soil or within gall tissue.

Females oviposit into developing Carya leaves, inducing characteristic galls that provide shelter and nutrition for larval development.

Functions as a gall-forming herbivore; galls may provide microhabitats for secondary inhabitants and influence leaf-level resource allocation in host trees.

No documented economic importance; minor curiosity for naturalists studying plant-insect interactions.
