Palaearctic. Fennoscandia South to Northern Spain. Ireland eastwards through North and Central Europe. Mountains of Italy, Yugoslavia). East into European and Russian Far East and Siberia to the Pacific coast (Kuril Islands)[8][9]
Habitat: Fagus, Quercus and Betula woodland, alluvial deciduous forest, Pinus, Picea and Abies forest.[10] Clearings, tracksides and arboreal, descending to visit flowers of white Umbelliferae Acer platanoides, Acer pseudoplatanus, Allium ursinum, Berberis, Caltha, Crataegus, Endymion, Euphorbia, Frangula alnus, Ilex, Lonicera xylosteum, Potentilla erecta, Prunus cerasus, Prunus spinosa, Ranunculus, Rubus idaeus, Salix, Sambucus, Sorbus aucuparia, Stellaria, Taraxacum.[11] The flight period is April to June (later at higher altitudes and more northerly latitudes).
D. venustus is known to be the most frequent and widely distributed species of the genus. Studies have indicated a very high morphological and genetic variability of D. venustus, suggesting that it is a complex of species. [12][13]
