Species Account

Most records are of leaf-mines.

Sutton & Beaumont, 1989: Widespread and fairly common in all five vice-counties.

2013 (CHF): This is a common moth across the county where the larvae mine leaves of rowan. The mines are usually typical but must be separated from those of Stigmella magdalenae which have linear frass with clear margins and just occupy a small part of the leaf. The other pitfall is Stigmella oxyacanthella which on occasions has been known to mine rowan - the mines can be remarkably similar but leaves are tenanted in September and October whereas nylandriella mines in July and August. A typical nylandriella mine is a long gradually widening corridor which often closely follows the leaf margin for a long distance. The frass is initially in a broad central line and usually becomes coiled or sometimes just thicker, leaving narrow clear margins. Mines with linear frass are longer and wider than those of Stigmella magdalenae and less confined to a small space.
