Resseliella clavula
Dogwood Club Gall Midge, Dogwood Clubgall Midge
Resseliella clavula is a gall midge in the family Cecidomyiidae that induces distinctive club-shaped galls on flowering dogwood (Cornus florida). The species is known to alter host plant reproduction and architecture, causing infested trees to produce more flowers but fewer fruits. Galled branches exhibit increased branching and shortened internodes compared to ungalled branches.
