    Description: Faunistics and ecology of the syrphid genus Epistrophe in The Netherlands (Diptera: Syrphidae) Ten species of Epistrophe have been found in the Netherlands, two of which, E. cryptica and E. similis, are recorded here for the first time. The distribution, changes in distribution and ecology of the species were investigated and are illustrated by distribution maps and diagrams of the flight period. In all species, except E. eligans, females were observed more than males. Furthermore, females seem to be active later in the season than males. It is discussed that this is probably caused by the differences in behaviour between the males of the species.

    De zweefvlieg Cheilosia psilophthalma, een dubbelganger van Cheilosia urbana, nieuw voor Nederland (Diptera: Syrphidae) (2001)

    Description: The hoverfly Cheilosia psilophthalma, a double of C. urbana new to the Netherlands (Diptera: Syrphidae)\nThe hoverflies Cheilosia psilophthalma Becker, 1894 and C. urbana (Meigen, 1822) are very similar in their appearances. Until recently, only C. urbana had been recorded from the Netherlands, but now C. psilophthama was found in Dutch collections as well. Both species occur on sandy soil, where they can be found on willow catkins in early spring. The identification is discussed and a key to the species is given.
