Mine entirely like that of Heterarthrus cuneifrons: a large upper-surface (but virtually full depth) blotch, without a trace of an initial corridor, starting in the centre of the leaf. Full grown larval in a discoidal cocoon in the mine. In the end the cocoon drops out if the mine, taking a disk of upper epidermis with it.
Sapindaceae, narrowly oligophagous
The only Heterarthrus on norway maple.
Fully developed mines in July.
Not known from the Benelux countries (Fauna Europaea, 2008).
distribution within Europe
Described from Georgia; within Europe known only from Sweden and Germany (Liston, 1995a); as demonstrated by the pictures also in Hungary.
Phyllotoma aceris: Hering (1957a), Wahlgren, 1944a, 1951a.
Between the Russian and Hungarian larvae shown above conspicuous differences are recognisable in extent and number of the ventral and also dorsal (mesothorax) spots. This may be due to the younger age of the Russian larva; but also regional differences may exist.
