Laburnum Leaf-miner Leucoptera laburnella
This species is most similar to Broom Bent-wing Leucoptera spartifoliella.
This was my first Leucoptera caught in my garden in 9 years. I was pretty sure about the ID based on the extent of orange scales around the tornal spot but this can be difficult to judge on worn individuals and this wasn't the freshest. To be safe (and to gain experience ahead of catching an even more worn one where examining the genitalia would be crucial) I checked the genitalia and this confirmed the ID.
