Liriomyza hieracii

Liriomyza hieracii (Kaltenbach, 1862)


Primary upper-surface blotch. Pupation outside the mine.


Asteraceae, narrowly oligophagous

Hieracium laevigatum, lachenalii & subsp. cruentifolium, murorum, sparsum; Pilosella officinarum.


BE not recorded (Fauna Europaea, 2008).

NE Accepted by Beuk (2002a) on the basis of a reference by Kabos (1971a) of blotch mines of L. hieracii on, among other genera, Hieracium. However, this can also indicate L. hieraciivora Spencer. Personally I found this type of mine only once in the Netherlands (H. laevigatum, Orvelte), but it was not possible to associate it definitely with one of the two species.

LUX not recorded (Fauna Europaea, 2008).

distribution within Europe

From Scandinavia to the Pyrenees and the Alps, and from the UK to Poland (Fauna Europaea, 2008); also Bulgaria (Buhr, 1941b; Beiger, 1980a).


De Meijere (1925a) described the larva of “L. hieracii”, but his material was a mix of hieracii, sonchi and taraxaci. All species of this group seem to have rear spiracula with ca. 8 papillae.


Much confusion has surrounded this species. De Meijere (1924a, 1925a) considered it a Dutch species, but in his final checklist (1939a) he synonymized L. hieracii (Kaltenbach) with L. sonchi Hendel, and L. hieracii sensu de Meijere with L. taraxaci Hering. Hering (1957a) considerered the species a synonym of L. pusilla (Meigen). Finally Spencer (1971a) unraveled the knot and concluded that L. hieracii mines exclusively on Hieracium.
