Andricus stellaris explained

Andricus stellaris, the sunburst gall wasp, is a fairly common species of cynipid wasp that produces galls on blue oaks and Oregon oaks on the Pacific coast of North America.^{[1] [2]} The wasp oviposits on the underside of leaves, between the lateral veins; the larval chamber is the brightly colored spot at the center of the gall. The chamber is surrounded by a crystalline structure.^[3]
