ATHYRIUM. Lady-ferns. [Woodsiaceae]

Three species of Athyrium are recorded in Britain. These include Alpine Lady-fern (A. distentifolium) and Lady-fern (A. filix-femina). The BSBI provide a downloadable plant crib for Athyrium.

Two British miners are recorded on Athyrium.

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

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

1# > ? Leaf / Stem-miner: In leaf stems and fronds (Ackland in Chandler, 1978: 227).

On Matteucia and Pteridium, but not yet on Athyrium, in Britain and elsewhere and in addition Athyrium elsewhere. Widespread in Britain and continental Europe.

Chirosia cinerosa (Zetterstedt, 1845) [Diptera: Anthomyiidae].

1 > Leaf-miner: Large full depth blotch, covering the entire distal part of a pinnula. The mine begins near the top, where an elliptic egg shell is attached to the underside of the rachis. Larva solitary. The mine contains much frass.

An upperside blotch at the tip of a pinna lobe.

On Pteridium and Dryopteris, but not yet on Athyrium, in Britain and continental Europe and additional other genera of ferns elsewhere. Widespread in Britain and continental Europe. Also recorded in East Palaearctic and Near East.

Chirosia histricina Rondani, 1866 [Diptera: Anthomyiidae].
