Andricus gigas Feron gigas, also known as the saucer gall wasp, is a species of gall-forming wasp in the genus Feron.

The galls produced by its all-female generation, which emerges in winter, are 3-4 mm wide, circular with raised edges.

They are red, pink, brown, or purple.

The larval chamber exists as a raised bump in the gall's center.

The bisexual generation produces galls that are brown and cone-shaped.
