Three major species of egg parasitoids (Hymenoptera) attack the egg masses of the pine processionary moths: Ooencyrtus pityocampae Mercet (Encyrtidae) Baryscapus servadeii Graham (Eulophidae) and Trichogramma sp. (Trichogrammatidae).
The suggested key aims at assisting those non-taxonomy persons who study the moth.
Six morphological characteristics are suggested to distinguish between the parasitoids: (1) the antennae, (2) the shape of the head, (3) the forewings, (4) the thorax, (5) the fore segments of the gaster, and (6) the tarsus.
Two minor species and three rare species are also listed.
