Plant Parasites of Europe

leafminers, galls and fungi

Agromyza alnibetulae

Agromyza alnibetulae Hendel, 1931

>Agromyza alnibetulae: mine on Betula pubescens

Betula pubescens, Maarn


Betula pubescens, Hilversum


An unusually long, upper-surface corridor that widens only little and winds freely through the leaf. Frass in two neat rows. Pupation outside the mine; exit slit (always?) in the lower epidermis.


Betulaceae, monophagous

Betula pendula, pubescens.


Mines are found from May till October.


BE recorded (De Bruyn & von Tschirnhaus, 1991a).

NE recorded (de Meijere, 1939a).

LUX recorded (Ellis).

distribution within Europe

From Norway to Italy, and from Ireland to Romania (Fauna Europaea, 2007); Bulgaria (Buhr, 1941b), Slovenia (Maček, 1999a).



Untill about 1970 one believed that a single Agromyza species lived on Alder and Birch, which was called A. alnibetulae. Only then Spencer (1969a) noted that in fact two species were involved, A. alnibetulae living only on Birch, A. alnivora only on Alder.

Agromyza albitarsis Zetterstedt 1848, nec Meigen, 1830.


Hering (1957a) writes that very rarely “A. alnibetulae” occurs on Carpinus. Obviously, it cannot be decided whether this remark concerns alnibetulae or alnivora.


As explained above, references without host plant information, published before 1970, are unreliable.
