Leaf-mine: A long narrow greenish/yellowish mine. Pupation in leaf at end of mine (Spencer, 1976: 220). Long upper-surface corridor, mainly in the top half of the blade. The mine descends, but changes direction a few times (up, down, up). Frass in one big lump. Puparium in the mine, fastened ventrally in the mine with dried frass (Bladmineerders van Europa). The mine is a long gallery which is formed mostly in the apical parts of the leaf (British leafminers). Larva: The larva is described by de Meijere (1938, as sönderupi), Beri (1971a) and Nowakowski (1973). Puparium: Can be yellowish but is more normally dark brown; posterior spiracles are on a low projection directed dorsally above the anus each with one long curving bulb and two smaller ones folded around its base (Spencer, 1976: 220-1, fig. 380). Comments: Carex ovalis is treated as Carex leporina (Oval Sedge) by Stace (2010). Hosts in Britain:

Time of year - mines: February. Time of year - adults: Unknown. Distribution in Great Britain and Ireland: Widespread in Britain including London (Hampstead), Sussex (Rusper), Middlesex (Scratch Wood), Oxford (Bagley Wood) (Spencer, 1972: 101), Surrey (Ash Vale) (British leafminers) and Warwickshire (Little Packington) (Robbins, 1991: 133); Cambridgeshire and North Ebudes (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).
