Cosmopterix pulchrimella

I found a single mine of Cosmopterix pulchrimella on Pellitory-of-the-wall at Pennard Pill (SS541884) yesterday. I think this is only the second VC41 record of this recent Welsh colonist following mines at Port Eynon in 2013.

I've looked for mines in Cardiff without success, but Pellitory is quite thin on the ground here and usually growing on sunny pavement edges (the moth prefers shaded plants with larger leaves). Worth keeping an eye out for the mines if you spot any Pellitory.
