Liriomyza graminivora Hering, 1949b. Notul ent. 28: 18
Liriomyza graminivora Hering, 1949b; Spencer, 1990. Host specialization in the World Agromyzidae (Diptera) : 355, 356, 372 (figs 1403-4), 373.

Leaf-miner: Upper surface corridor mine. The mine starts at the leaf apex. Frass in clumps or closely packed grains (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.

Posterior spiracles of the larvae with 9-11 bulbs (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).

Comments: Although tentatively recorded by Robbins (1991: 140) and Pitkin & Plant), Liriomyza graminivora is not listed as a British species by Henshaw in Chandler, 1998.
