Sutton & Beaumont, 1989: Local among broom.
2013 (CHF):Most of our records are of adult moths, however the larval mines should be looked for on broom as this species might be more common than we suspect. The mine is a long black straight gallery which passes down the twig initially. The mine then changes direction and the spaces between the ridges stain black as the mine fills them. The branches may appear stained black as the mines develop and a plant with many mines can often be recognised from a distance. The yellow larva is hardly visible in the mine.
