Stem-mine: A shallow external stem-mine (Spencer, 1972b: 29).

The 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).

Comments: Lychnis flos-cuculi is treated as Silene flos-cuculi (Ragged-Robin) by Stace (2010).
