The leaf and stem mines of British flies and other insects

(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

ECHINARIA. Echinaria. [Poaceae]

Only one introduced species of Echinaria is recorded in Britain.

Only one British miner is recorded on Echinaria.

Nearly 100 British miners or possible miners are recorded on grasses in Britain.

It is recommended that adults of all miners on grasses be reared to be certain of their identity.

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Echinaria

1 > Leaf-miner: Larvae either singly or several in leaf, then forming large blotch-mine, feeding first up and then down the leaf. Pupation external (Spencer, 1976: 119).

Shallow upper-surface corridor, without full-depth sections, starting high in the leaf. Initially the corridor runs up, but soon it changes direction, quickly widening. In Deschampsia generally one mine per leaf, occupying its entire width; in Glyceria there mostly are serveral mines that merge in the end. Pupation outside the mine; the puparium often sticks to the leaf.

Puparium black or dark red

On Dactylis, Deschampsia and Glyceria, but not yet on Echinaria, in Britain and Deschampsia, Echinaria and Glyceria elsewhere. Widespread in Britain and continental Europe. Also recorded in Canada.

Agromyza lucida Hendel, 1920 [Diptera: Agromyzidae].
