Leaf-mine: The larva makes several full depth blotch mines (Bladmineerders van Europa).

Larva: Steyskal (1970a, as P. mixta) gives a detailed description. The most remarkable detail is the strongly enlarged basal tooth of the mandible (Bladmineerders van Europa).

Puparia: Unknown,

Comments: A serious pest on spinach and beet crops (Michelsen and Baez, 1985a). Pegomya exilis and Pegomya cunicularia were distinguished from Pegomya betae and Pegomya hyoscyami by Michelsen (1980). Material of both [the former species] had previously been assigned to those [two latter] species (Chandler, pers. comm.).

Hosts in Britain: Unknown.

Hosts elsewhere:

Time of year - mines: Unknown.

Time of year - adults: Unknown.

Distribution in Great Britain and Ireland: Michelsen (1980) distinguished specimens of Pegomya cunicularis from specimens previously mis-identified as Pegomya betae or Pegomya hyoscyami. It is not known whether any of this previously mis-identified material is British. Recorded from Ayrshire,
Cambridgeshire, East Kent, Edinburgh, Glamorgan, Huntingdonshire, Linlithgow, North Somerset, West Cornwall, Westmorland and Zetland (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).
