Feron kingi, commonly known as the red cone gall wasp, is a member of the Cynipidae family.
The adult female lays her eggs within the leaves of several white oak species, including the valley oak (Quercus lobata). Once the egg hatches, the larva begins feeding on the leaf tissue, triggering the plant to form a hard, protective structure—a small red cone about 5 mm tall. This gall benefits the insect, providing it with additional plant tissue to consume. Inside the gall, the larva pupates and eventually matures into a parthenogenetic female adult before emerging from the tip of the cone. That’s right — there are no male gall wasps.
