Mymarommatoidea
fairyfly-like parasitic wasps
Mymarommatoidea is a minute superfamily of parasitoid wasps containing a single extant family, Mymarommatidae, and three extinct families known from Cretaceous amber. Adults measure approximately 0.3 mm in length, making them among the smallest insects. The superfamily remained without a confirmed host record for nearly a century until 2022, when a Hawaiian species was documented as an egg parasitoid of barklice (Psocodea). Most described species are fossils; extant species are globally distributed but easily overlooked due to their microscopic size.
