What species of moth is this please? It's not one I've come across before. Location is north-east London.

Hi Nick,
I reckon that is a Box Tree Moth (Diaphania perspectalis)... a fairly recent arrival to the UK and obviously spreading.

Many thanks Trev. Seems like it's something of a pest ... now I don't feel so bad about being a complete muppet the following morning by accidentally treading on it
