Ophiomyia nasuta Melander, 1913
[Diptera: Agromyzidae]

Agromyza nasuta Melander, 1913. Jl. N. Y. ent. Soc. 21: 260, as a var. of maura
Ophiomyia nasuta (Melander, 1913). Spencer, 1976. Fauna ent. Scand. 5(1): 71-2, figs 87-8.

Leaf-mine: Larva mines from the midrib. Pupation in the base of the hollow midrib (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.

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.

Hosts elsewhere:

Taraxacum       Spencer, 1976: 72
Taraxacum officinale Dandelion British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - larvae: Currently unknown.

Time of year - adults: Currently unknown.

Distribution in Great Britain and Ireland: Added to the British checklist by Gibbs (2006a).

Distribution elsewhere: Widespread in continental Europe including Austria, Germany, [former] Czechoslovakia, the [former] U.S.S.R., Denmark, Sweden and Finland (Spencer, 1976: 71), Belarus, Czech Republic, Estonia, French mainland, Germany, Hunagry, Lithuania, Poland, Slovakia, Spanish mainland and Switzerland (Fauna Europaea).

Also recorded in the East Palaearctic (Fauna Europaea) and Canada (Spencer, 1976: 71).
