EPALTES. Spreading Nut-heads. [Asteraceae]


Only one species of Epaltes, Spreading Nut-heads (E. australis), is recorded in Britain. It is introduced.

Only one British miner is recorded on Epaltes.

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



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


1 > Leaf-miner: An irregular linear mine, which in small leaves can form a secondary blotch.

Long, upper-surface corridor, winding through the leaf and frequently crossing itself; in small leaves often a secondary blotch in the end. Frass in short strings and pearl chains. Pupation outside the mine.

An irregular gallery, sometimes crossing over, with black frass arranged as elongate very narrow streaks at the sides of the mine .

On Aster, Bellis and Solidago, but not yet on Epaltes, in Britain and additional genera of Asteraceae elsewhere. Widespread in Britain. Also recorded in the Republic of Ireland. Widespread and common in much of continental Europe.

Liriomyza pusilla (Meigen, 1830) [Diptera: Agromyzidae].
