Leaf-mine: Similar to the mine of Pegomya hyoscyami, but differs in the presence of an unusually large puparium. Probably a better discrimination is the unusually large clutch size, which is on averge is eleven (Bladmineerders van Europa).

Larva: Details unknown.

Puparia: Details unknown.

Comments: Ackland in Chandler (1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere

Hosts in Britain:

Hosts elsewhere:

Time of year - mines: Unknown.

Time of year - adults: Unknown.

Distribution in Great Britain and Ireland: Warwickshire (Robbins, 1991: 98); Cambridgeshire, Herefordshire and Oxfordshire (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).

Distribution elsewhere: Recorded from Spanish mainland. Doubtfully recorded from Germany, Poland and Sweden (Michelsen, in Fauna Europaea).
