Callicera Fagesii

	Callicera Fagesii ''Callicera'' is a Holarctic genus of hoverflies Medium-sized to rather large (wing length 9·75–15 mm.) bumblebee mimics. They are beautiful metallic flies, with strikingly long antennae. All the species are considered rare. ''Callicera'' larvae live in water rot-holes of overmature trees as saprophages. They occur mainly in ancient forests where they are arboreal. Peck, L.V. (1988) Syrphidae. In: Soos, A. & Papp, L. (eds.) ''Catalogue of Palaearctic Diptera'', 8: 11–230. Akad.Kiado, Budapest.

	Johann Wilhelm Meigen Johann Wilhelm Meigen (3 May 1764 – 11 July 1845) was a German entomologist famous for his pioneering work on Diptera. Life Early years Meigen was born in Solingen, the fifth of eight children of Johann Clemens Meigen and Sibylla Margaretha Bick. His parents, though not poor, were not wealthy either. They ran a small shop in Solingen. His paternal grandparents, however, owned an estate and hamlet with twenty houses. Adding to the rental income, Meigen's grandfather was a farmer and a guild mastercutler in Solingen. Two years after Meigen was born, his grandparents died and his parents moved to the family estate. This was already heavily indebted by the Seven Years' War, then bad crops and rash speculations forced the sale of the farm and the family moved back to Solingen. Meigen attended the town school but only for a short time. He had learned to read and write on his grandfather's estate and he read widely at home as well as taking an interest in natural history.
