Phylloxera spinosa
(Shimer, 1869)
Phylloxera spinosa is a gall-forming insect in the Phylloxeridae, closely related to aphids. This induces distinctive galls on its plants through chemical secretions that manipulate plant tissue development. Like other phylloxerans, it has a complex involving multiple and winged forms. The species was described by Shimer in 1869 and is currently accepted as valid.
