Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Triglochin
|
1a > Leaf-miner: A long narrow leaf-mine which winds round the filiform leaves and
can penetrate deeper into the parenchyma, becoming invisible. Pupation
internal (Spencer, 1976:
230).
Narrow
corridor, spiralling around the leaves. Often part of the corridor
in the deeper layers of the leaf. Frass in strings. Pupation generally
within the mine. |
On Triglochin maritimum and Triglochin palustre in
Britain and elsewhere. Only recorded from Kent, Dorset,
Suffolk in Britain. Widespread in continental Europe.
|
Liriomyza
angulicornis (Malloch, 1918) [Diptera: Agromyzidae]. |
1b > Leaf-miner: Narrow corridor, spiralling around the leaves; often a part of the
mine runs in the deeper parts. Frass in strings, but not in the
typical pattern. Pupation as a rule within the mine. |
On Triglochin in Britain. On Triglochin maritimum and Triglochin palustre elsewhere. Only known from Suffolk
in Britain. Widespread in continental Europe.
|
Liriomyza
latipalpis Hendel, 1920 [Diptera: Agromyzidae]. |
1c > Leaf-miner: Broad, transparant (full depth) gallery. Pupation external.. |
On Triglochin in Britain and elsewhere. Distribution in
Britain unknown. Widespread in continental Europe.

Scrobipalpa
stangei (E. Hering, 1889) [
Lepidoptera:
Gelechiidae]. |
