Ophiomyia melandricaulis Hering, 1943; Spencer, 1990. Host
specialization in the World Agromyzidae (Diptera) : 63. 69,
A shallow external stem-mine (Spencer, 1972b: 29).
mine generally starts as a fine, lower-surface, corridor the seems
to end upon a thick vein. In reality the corridor continues by way
of the petiole to the stem, where a very long mine is formed in
the rind. Frass in widely spaced grains. Pupation within the mine,
mostly just above a node; the anterior spiracles penetrate the epidermis
(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.
The larva is briefly described by de Meijere (1943).
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).
Pale brown; posterior spiracles each with 8-11 bulbs (Spencer, 1972b: 29).
Lychnis flos-cuculi is treated
as Silene flos-cuculi (Ragged-Robin)
by Stace (2010).
