Gall-former: Larva feeding in the mid-rib or flower stalk where a gall-like swelling is produced (see also Redfern et al., 2002: 453, fig. 914). Pupation at base of leaf, near exit hole prepared by larva prior to pupation (see also Redfern et al., 2002: 453, figs 915).

The larva lives in a corridor of just a few cm long within the midrib. The leaf is stunted and the midrib is strongy swollen, gall-like. In the end the mine turns red. Pupation within the mine, near a previously made exit in the upper surface of the mine (Bladmineerders van Europa).

Larva: Details unknown.

Puparium: Details unknown.

Distribution in Great Britain and Ireland: Widespread, at least in south.

Also recorded in the Republic of Ireland (Martinez in Fauna Europaea).
