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


1 > Leaf-miner: A narrow linear mine, even in the finest subdivisions of the leaves (Spencer, 1972b: 77, as matricariae ; Spencer, 1976: 478).

Very fine corridor, upper- or lower-surface, even in the narrowest leaf segments. The corridor may be up to 14 cm long (Sehgal, 1971a). Generally the corridor descends towards the leaf base. Frass in pearl chains of loose grains, hardly in strings. Pupation outside the mine. Very fine corridor, upper- or lower-surface, even in the narrowest leaf segments. The corridor may be up to 14 cm long (Sehgal, 1971a). Generally the corridor descends towards the leaf base. Frass in pearl chains of loose grains, hardly in strings. Pupation outside the mine.

On Achillea millefolium, Anacyclus pyrethrum, Anthemis, Tanacetum vulgare, Tripleurospermum, Tripleurospermum maritimum and Tripleurospermum maritimum x inodora in Britain and other Asteraceae elsewhere. Widespread in Britain and continental Europe. Also recorded in Canada.

Phytomyza pullula Zetterstedt, 1848 [Diptera: Agromyzidae].
