Abstract

The hoverfly Criorhina ranunculi –
a biodiversity indicator at the landscape level?
The hoverfly Criorhina ranunculi is rare and red-listed
in Sweden, but it may be overlooked. I made a detailed
inventory of the species in the parish of Stenbrohult,
southern Sweden, where the species was found
at nine localities in 2006, at one of these with at least
ten individuals. The study area, with many other redlisted
woodliving insects (Nilsson & Baranowski 2003),
contains over 500 old hollow trees. I suggest that
Criorhina ranunculi may indicate valuable areas for
conservation action at the landscape level. The species
was found at many flowering shrubs and trees (Salix,
Malus, Prunus, Acer, Crataegus, Syringa) from the
beginning of May to the beginning of June. Spring
was relatively late in 2006.
