Distribution:
Iceland south to the Pyrenees and northern Spain; from Ireland and Fennoscandia eastwards through much of central and northern Europe and Russia to the Pacific coast and Japan.
Habitat:
Deciduous and coniferous forest, also in adjacent open areas, like heaths, grassland and in parks.
Description:
Dasysyrphus tricinctus has a body length of 9 - 12 mm. Thorax and abdomen have a shiny black base color. The thorax is monochrome and without markings. The abdomen shows some yellow markings. On the third segment there is a broad and on the 4th a narrow in the middle interrupted yellow stripe. The 2nd segment is either completely black or has two small yellow spots. The eyes are hairy.
Biology:
Dasysyrphus tricinctus flies in 2 generations from April to October. Adults are mainly active in April/May and in August/September. They visit a wide range of flowers, including yellow composites, white umbellifers, Calluna, Campanula, Convolvulus, Cornus, Euphorbia, Geranium, Parnassia, Plantago, Polygonum, Ranunculus, Sedum, Sorbus, Stellaria, Succisa and Valeriana.
