Ptochomyza asparagi Hering, 1942
Diminutive mines in the “needles”. Rarely, but then in large numbers, also in the rind of thin branches. One leaf is completely mined out, sometimes the larva migrates to a second one. Puparium in the mine, either in the base or in the tip (Hering, 1942a; Spencer, 1973b).
No damage to mention (Darvas, Skuhravá & Andersen, 2000a; Spencer, 1973b).
Mines in August (Hering, 1957a).
Not known from the Benelux countries (Fauna Europaea, 2008).
distribution within Europe
From Lithuania to the Iberian Peninsula, and from France to Hungary (Fauna Europaea, 2008).
The larvae are extensively described by de Meijere (194a). They are rather aberrant, with anterior spiracula on long stalks and strongly elongated spinelike rear spiracula.
