Leaf / Stem mine: The mine starts in the leaf but the larva moves to the stem (Spencer, 1976: 316).

The mine starts in a leaf, that soon wilts (to find the mine, look for this detail). Next the larva continues as a miner of the skin of the stem (Bladmineerders van Europa).

Larva: The larva is described by de Meijere (1941).

Puparium: Posterior spiracles each with about 20 bulbs (Spencer, 1976: 316).

Comments: Galium mollugo is treated as Galium album (Hedge Bedstraw) by Stace (2010).

Hosts in Britain: Unknown.

Hosts elsewhere:

Time of year - larvae: June-July (Bladmineerders van Europa).

Time of year- adults: Unknown.

Distribution in Great Britain and Ireland: Added to British Checklist by Deeming (1999). Carmarthenshire and Glamorgan (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

NBN Grid map: Note that not all datasets on the NBN Gateway may be available on the map below. If you are an NBN Gateway registered user you can request access for missing datasets via the link 'Open interactive map in new window' below.

Distribution elsewhere: Widespread in continental Europe including Finland, Germany, The Netherlands (Spencer, 1976: 316), Balearic Is., French mainland and Lithuania (Martinez in Fauna Europaea).
