Sphecodes schenckii
Sphecodes schenckii is a solitary cleptoparasitic bee which is found in southern and eastern Europe and the Middle East. Its host is "Lasioglossum discum" and possibly "Halictus simplex" where "L. discum" does not occur such as in southern Germany and Switzerland. It is rare and there are only a few records from each country from which it has been recorded. It prefers warm open areas, such as grasslands and Mediterranean scrub, and may be threatened by reafforestation and vegetation succession. The specific name "schenckii" is in honour of the German Hymenopterist Adolph Schenck. References.
