Distribution. Europe, north to south Finland, Sweden and Denmark, south England, eastwards to Tajikistan (Westrich 1989, Warncke 1992, Sörensson et al. 2009, Madsen & Calabuig 2011).

Biology. Rare species of sandy sites, uncommon in the localities in most of European countries. This species is nest cleptoparasite of small species of Lasioglossum; L. minutissimum (Kirby) is a confirmed host (Alfken 1912). Vegter (1993) brought evidence of two additional hosts: L. leucopus and L. zonulum (Smith), which is possible. Other likely hosts are the following: L. lucidulum (Schenck) and L. sexstrigatum published by Vegter (1993) and L. morio mentioned by Westrich (1989). During our observations nests of L. punctatissimum and L. semilucens (Alfken) were also invaded by females of this species.
