(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

Hydrellia ranunculi Haliday, 1839
[Diptera: Ephydridae]

Hydrellia ranunculi Haliday, 1839. Ann. Mag. nat. Hist. 3: 402.

Leaf-miner: 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 record was British or Foreign and is therefore included under 'Hosts in Britain and/or elsewhere'.

Hosts in Britain and/or elsewhere:


? Nasturtium

officinale Water-cress 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 and Ireland: Recorded in Britain by Irwin (1978) including Cambridgeshire, Cardiganshire, East Norfolk, North Essex, Nottinghamshire, Shropshire and South Lancashire (NBN Atlas).

Also recorded in the Republic of Ireland (Zatwarnicki, 2004 in Fauna Europaea).

Distribution elsewhere: Widespread in continental Europe including Austria, Azores, Balearic Is., Belgium, Bulgaria, Canary Is., Czech Republic, Finland, French mainland, Germany, Hungary, Italian mainland, Macedonia, Poland, Romania, Sardinia, Sicily, Slovenia, Spanish mainland, Sweden, The Netherlands, Ukraine and Yugoslavia (Zatwarnicki, 2004 in Fauna Europaea).
