lamii Kaltenbach, 1858. Verh. naturh. Ver. preuss. Rheinl.
Amauromyza lamii (Kaltenbach, 1858); Spencer, 1990. Host
specialization in the world Agromyzidae (Diptera) : 204, 205,
a long, slim corridor, the frass alternating on either the side
of the corridor. After moulting, the larva broadens the mine and
the frass is less regular. Pupation external (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 described by Dempewolf (2001a) and de Meijere (1934). Rear spiraculum with three bulbs; the posterior one not conspicuously enlarged or curved; this separates both A. lamii and morionella from A. labiatarum, by far the commonest Amauromyza on Lamiaceae (Bladmineerders van Europa).
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).
The posterior spiracular pore on the posterior spiracle is a little
larger than the other two and strongly bent (Bladmineerders van Europa).
The British record on Glechoma (Robbins, 1991: 103) is considered
unlikely to be correct (Henshaw in Chandler,
officinalis is treated as Betonica
officinalis (Betony) by Stace (2010).
