BASSIA. Summer Cypress. [Chenopodiaceae]

Four species of Bassia are recorded in Britain. All are introduced and include Summer Cypress (B. scoparia).

Only one British miner is recorded on Bassia.

A key to the European miners recorded on Bassia is provided in Bladmineerders van Europa.

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

1 > Leaf-miner: The mine begins as a short zigzagging corridor, that very soon becomes overrun by a large, perfectly transparent blotch. Frass in a big black central lump. In fresh mines something like primary feeding lines are recognisable, normally seen only in Diptera mines. Pupation external, exit a rather untidy hole

On Atriplex and Chenopodium, but not yet on Bassia, in Britain plus Amaranthus, Bassia and Spinacia elsewhere. Widespread in Britain and continental Europe.

Chrysoesthia sexguttella (Thunberg, 1794) [Lepidoptera: Gelechiidae].
