Aulagromyza discrepans (van de Wulp, 1871) [Diptera: Agromyzidae]

Aulagromyza discrepans van de Wulp, 1871. Tijdschr. Ent. 14: 206
Paraphytomyza discrepans (van de Wulp, 1871); Spencer, 1972b. Handbk ident. Br. Ins. 10(5g): 64.

Lifestyle: Unknown.

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.

The larva is described by Dempewolf (2001: 172).

Puparium: 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).

Hosts in Great Britain and Ireland: Currently unknown.

Comments: There is a record of Aulagromyza discrepans on Artemisia (Robbins, 1991), but as the mine has not previously been described, the record needs confirmation.

Hosts elsewhere: Currently unknown. Not in Spencer (1990).

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Surrey (Godalming), Middlesex (Scratch Wood), Cambridge (Chippenham), Suffolk (Orford) and Dunbartonshire (Bonhill) (Spencer, 1972b: 64); Cambridgeshire, Denbighshire, East Ross, South Lancashire and South-west Yorkshire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Germany (Dempewolf, 2001: 172), Balearic Is., Belgium, Crete, Czech Republic, French mainland, Poland, Slovakia, Spanish mainland and The Netherlands (Fauna Europaea).
