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).
