Diagnosis.

Length 5-9 mm. Both sexes are bicoloured with a green or blue head and mesosoma, and a golden red metasoma (Fig. 75). The vertex and the anterior margin of the pronotum often have golden reflections. The metasoma is very finely and densely punc tured on the tergites, causing the surface to appear dull (Fig. 75). The posterior margin of T3 is edentate. The species can be confused with similarly coloured species of Chrysura , but the radial sector vein of the forewing does not reach the wing margin (Fig. 10).

Distribution.

Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden. Relatively rare. - Trans-Palearctic/Holarctic? Europe, Asia, Russian Far East, China, USA, Canada ( Kimsey and Bohart 1991, Kurzenko and Lelej 2007, Rosa et al. 2014). Possibly accidentally introduced to North America ( Bohart and Kimsey 1982).

Biology.

Habitat: sparsely vegetated areas with clay or sandy soil, gardens with clay structures, such as barn walls. Adults occasionally visit flowers of Asteraceae , Crassulaceae and Rosaceae ( Kusdas 1956, Heinrich 1964, Ressl 1966, Linsenmaier 1997, Rosa 2004, 2006). Flight period: late May to mid-August. Host: Odynerus spinipes (Linnaeus) and Odynerus reniformis (Gmelin) ( Vespidae ) ( Smith 1862, Adlerz 1910, Trautmann 1927, Linsenmaier 1959, Banaszak 1980, Morgan 1984), possibly also Ancistrocerus parietum (Linnaeus) and Gymnomerus laevipes (Shuckard) ( Dahlbom 1854, Berland and Bernard 1938). Host records mentioning bees of the genera Osmia Panzer and Heriades Spinola ( Megachilidae ) are doubtful, as noted by Kunz (1994).
