Eupelmus messene
Eupelmus messene is a tiny parasitoid wasp in the family Eupelmidae. Females are brachypterous (short-winged) and reproduce via thelytoky, producing only daughters. The species is a specialized idiobiont ectoparasitoid of the gall wasp Aulacidea hieracii, attacking both concealed and exposed larvae and pupae of its host. Females possess a remarkably thin, flexible, and mobile ovipositor capable of drilling through hard substrates, including polystyrene Petri dish walls in laboratory observations.

The species is accepted in the Catalogue of Life and iNaturalist taxonomic databases, though direct observational records remain sparse.
