Pegomya exilis (Meigen, 1826)
[Diptera: Anthomyiidae]


Anthomyia exilis Meigen, 1826
Pegomya exilis (Meigen, 1826).


Leaf-mine: Mine indistinguishable from P. betae or P. hyoscyami (Bladmineerders van Europa).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

Puparia: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Comments: 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 Great Britain & Ireland: Currently unknown.

Hosts elsewhere:

Chenopodiaceae        
Chenopodium album Fat-hen British Wild Flowers by John Somerville et al. Bladmineerders van Europa
Chenopodium glaucum Oak-leaved Goosefoot British Wild Flowers by John Somerville et al. Bladmineerders van Europa
Spinacia oleracea Spinach   Bladmineerders van Europa

Time of year - mines: Unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: 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.). It is not known whether any of this previously mis-identified material is British.
