Sphecodes hyalinatus Hagens, 1882

Described as: Sphecodes hyalinatus Hagens, 1882: 222 . No synonyms.

Distribution. Most of the Europe to 68°N, rare in south Europe; absent from Turkey and North Africa (Westrich 1989, Warncke 1992).

Biology. Species of sunny sites in cooler regions, usually in rocky steppes on non-basic substrate. In central Europe local and usually rare. Two known hosts are Lasioglossum fratellum confirmed by Field (1996) and L. fulvicorne first mentioned by Stoeckhert (1933) as the likely host and since confirmed by Westrich (1989). The biology of L. fratellum and S. hyalinatus was studied by Heide (1992) and Field (1996). The abundance of this species is usually bound to the abundance of hosts. We have observed association of S. hyalinatus with both of the mentioned hosts.
