Notes: This species was reported from the Maltese Islands by Shaw & Horstmann (1997) from Bedellia somnulentella . Most rearing records of D. exareolator are from B . somnulentella ; however it has also been reared from other species in families such as Gracillaridae , Choreutidae and Yponomeutidae . Diadegma exareolator is a koinobiont endoparasitoid that attacks the host in its larval state and kills it in its cocoon ( Shaw & Horstmann, 1997 ).
