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 Mape.
Fully developed mines in July.
Not known from the Benelux countries (Fauna Europaea, 2008).
