leafy-wreath gall
Andricus stropus is a species of cynipid gall wasp in the family Cynipidae that induces distinctive galls on oak trees. The species is part of the highly diverse Andricus genus, which contains numerous oak-associated gall wasps, each producing characteristic gall structures. Like other cynipids, A. stropus has a complex life cycle involving manipulation of plant tissue through chemical secretions that redirect host oak growth patterns. The species is known from observations primarily in North America.
