The hoverfly Criorhina ranunculi – a biodiversity indicator at the landscape level?

Summary, in English

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.
