Cheilosia fasciata larva



Allium ursinum, Belgium, prov. Liège: La Calamine


same mine in transparency


Mine upper-surface, greyish; initially an irregularly branching corrisor, in the end a large blotch that can occupy almost an entire leaf. In transparency the egg is visible at the beginning of the mine, inside the parenchyma (unlike Pegomya species, where the egg is deposited at the outside). Frass scattered, greenish, deliquescent by moisture inside the mine.

host plants

Alliaceae, narrowly monophagous

Allium ursinum, victorialis.


Larvae in May-June (Hering, 1957a).


BE recorded ( Verlinden, 1991a).

NE recorded (de Meijere, 1939a).

LUX recorded (Fauna Europaea, 2007).

distribution within Europe

From Germany to the Pyrenees, the Alps and Bulgaria; also in Norway (Fauna Europaea, 2007)


See Rotheray (1990a) and Stuke (2000a) for a description of the larva.


Chilosia, Chilomyia, fasciata.


Even where the host plant occurs in large populations, the miner frequently is missing.
