Liriomyza asteris Hering, 1928
mine
Corridor from start to end. The mine begins lower-surface, very shallow, often long, branching several times or stellate; later the mine becomes upper-surface. Most frass in pearl chains. Pupation external, exit slit in upper epidermis.
hostplants
Asteraceae, monophagous
Aster amellus.
Buhr (1932a), with some hesitation, adds A. novae-angliae, now Symphyotrichum novae-angliae. Because neither species mentioned is spontaneously growing in Spain, there probably a third Aster species is involded.

Larvae in June and August (Hering, 1957a).
BENELUX
Not known from the Benelux countries (Fauna Europaea, 2009).
distribution within Europe
Germay, Czechia, Hungary, Spain (Surányi 1942a; Fauna Europaea, 2009).
larva
Yellow. The description of the larva by Beri (1971d), taken from Phlomis sp., should be disregarded.
