Diadegma exareolator Aubert, 1964

Material examined: MALTA, Selmun, 23–30. i.2010, 1 ♂, emerged from Bedellia somnulentella (Zeller) ( Lepidoptera : Lyonetiidae ), MZ, NMS; Ħad-Dingli, 12. iii.2009, 1 ♂, emerged from Dialectica scalariella (Zeller) ( Lepidoptera : Gracillaridae ) on Borago officinalis , MZ, NMS; Mosta Valley, 10. vi.2009, 1 ♀, emerged from Dialectica scalariella (Zeller) , MZ, NMS [parasitoids determined by Mark Shaw; hosts determined by Michael Zerafa].

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).
