Hydrellia mutata (Zetterstedt, 1846)
[Diptera: Ephydridae]

Notiphila mutata Zetterstedt, 1846. Dipt. Scand. 5: 1876.
Hydrellia mutata (Zetterstedt, 1846).

Leaf-mine: Details 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.

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).

Comments: Irwin and Chandler in Chandler (1978) did not indicate whether their host records are British or Foreign and are therefore tentatively included under 'Hosts in Britain and/or elsewhere' as are the records by Pitkin & Plant, which were previously assumed to be British. The record of this species on Lemna is dicounted.

Hosts in Britain and/or elsewhere:

? Alisma plantago-aquatica ? Water-plantain British Wild Flowers by John Somerville et al. Irwin and Chandler in Chandler, 1978: 225
? Hydrocharis morsus-ranae ? Frog-bit British Wild Flowers by John Somerville et al. Irwin and Chandler in Chandler, 1978: 225
? Stratiotes       Pitkin & Plant
? Stratiotes aloides ? Water-soldier British Wild Flowers by John Somerville et al. Irwin and Chandler in Chandler, 1978: 225

Time of year - mines: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: Recorded in Britain (Irwin and Chandler in Chandler, 1978); Cambridgeshire, Dorset, East Kent, Glamorgan, Huntingdonshire, Monmouthshire, South Hampshire, SOuth-west Yorkshire and West Gloucestershire (NBN Atlas).

Distribution elsewhere: Widespread in continental Europe including Austria, Belgium, Czech Republic, Germany, Hungary, Poland, Sweden and The Netherlands (Zatwarnicki, 2004 in Fauna Europaea).

NBN Atlas links to known host species:

? Alisma plantago-aquatica, ? Hydrocharis morsus-ranae, ? Stratiotes aloides

British and Irish Parasitoids in Britain and elsewhere: Currently unknown.
