Caryomyia echinata, the hickory spiny gall midge, is a species[1] of gall midge in the family Cecidomyiidae, occurring in Eastern North America.

[2] "The name echinata is a Latin adjective meaning spiny, with reference to the long, stiff hairs covering the gall."

[4] Pupae emerge in late summer through the side of the gall near the base.

[3]: 50 "This gall is the only woody Caryomyia gall that is covered with very long, stiff hairs and occurs between instead of on veins."
