Leaf-mine: A linear-blotch mine, often with several mines occurring in the same leaf (Spencer, 1976: 167, fig. 305).

A short, mostly upper-surface, rarely partly lower-surface corridor leads to a large, upper-surface, primary blotch. The mine initially is pale, turns brown later. Frass in sizeable dispersed grains. Pupation outside the mine; the larva leaves the mine through a semicircular exit slit in the upper epidermis (Bladmineerders van Europa).

Upper surface variable mine, from a short gallery leading to a large, roundish blotch to a long gallery leading to an elongated blotch (British leafminers).

Larva: The larva is described by de Meijere (1925), Dempewolf (2001: 104) and illustrated in Bladmineerders van Europa.

Puparium: Orange-yellow; posterior spiracles each with 3 bulbs (Spencer, 1976: 167).

Time of year - mines: June-November.

Time of year - adults: Unknown.

Distribution in Great Britain and Ireland: Widespread in Britain including Hampshire (Fleet) (British leafminers), Surrey (Box Hill), Isle Of Wight (Brading), Devon (Torcross), Cornwall (Lizard), Hereford (Woolhope) (Spencer, 1972: 46), Warwickshire (Coventry and Warwick) (Robbins, 1991: 91), London, South Kensington, Natural History Museum Garden (Martin Honey, pers. comm.); East Sussex, 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).

Also recorded in the Republic of Ireland (Dublin) (Spencer, 1972: 46).

Distribution elsewhere: Widespread in continental Europe, including Denmark, Norway, Sweden (Spencer, 1976: 167), The Netherlands, Luxembourg (Bladmineerders van Europa), Belgium (de Bruyn and von Tschirnhaus, 1991), Germany (Spencer, 1976: 550; Dempewolf, 2001: 104), Czech Republic, French mainland, Italian mainland, Lithuania, Republic of Moldova, Romania, Sardinia, Spanish mainland, Switzerland and Yugoslavia (Martinez in Fauna Europaea).

Empty mines on Buddleja paniculata from Sunda in the Himalayas, N.W. India were identified by Spencer (1990) as Amauromyza verbasci.
