Hoverflies Cheilosiini
 |
| 29 May 2021 |
Cheilosia is a genus of hoverfly. Most Cheilosia are black or largely un-coloured, lacking the bright colours and patterns of many hoverfly species. It is one of the most species diverse genera of hoverflies. The biology of many species is little understood, but where known, the larvae of Cheilosia species feed in the stems of plants or in fungi.
Cheilosia albitarsis and Cheilosia ranunculi are very similar and can often only be safely determined by detailed examination. Any specimen that has not been subjected to detailed examination should be submitted as Cheilosia albitarsis/ranunculi agg. They are robust with a short broad abdomen. In sunlight the thorax may be seen as metallic dark blue/green. The abdomen is more of a duller grey/bronze colour. (Nature Spot)
