Chromatomyia farfarella (Hendel, 1935)
mine
Upper-surface, less often lower-surface corridor. Frass in isolated grains. Puparium within the mine, usually at the lower surface, white or yellowish white in colour. Front spiracula penetrate the plant epidermis as fine brown hooks.
host plants
Asteraceae, oligophagous
Leontodon; Taraxacum officinale.
phenology
Probably bivoltine (Robbins, 1991a).
BENELUX
Not known from the Benelux countries (Fauna Europaea, 2007).
distribution within Europe
From Scandinavia to the Pyrenees, and from Ireland to Poland; also Iceland and Serbia (Fauna Europaea, 2007); also Portugal (Černý ao, 2018a).
larva
Rear spiraculum with 6-9 papillae.
synonyms
Phytomyza farfarella.
notes
According to the available literature only adult specimens can be distinguished from farfarella‘s close relatives Ch. horticola and syngenesiae. Griffiths (1967a) remarks that farfarella, contrary to the other two species seems to be restricted to undisturbed habitats.
The species is not mentioned in the keys by Hering (1957a).
