Leaf-mine: A narrow, whitish linear mine. Pupation internal (Spencer, 1976: 416).

Upper-surface, less often lower-surface corridor. Frass in isolated grains. Puparium within the mine, usually at the lower surface (Bladmineerders van Europa).

Larva: Posterior spiracles with 6-9 bulbs (Bladmineerders van Europa).

Puparium: White (Spencer, 1976: 416).

Comments: Leontodon autumnalis is treated as Scorzoneroides autumnalis (Autumn Hawkbit) by Stace (2010).

Distribution in Great Britain and Ireland: Herefordshire (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 (Co. Clare, Ballyvaughan, Lough Rask) (Spencer, 1972: 87).
