A nugget of gold

This turned up in the garden last night. A Golden Plusia:

Resting on its foodplant: Aconitum.

There are only a handful of county records and oddly enough, all from one year: 1987. It's almost exclusively a garden moth due to its foodplants. The moth colonised the UK towards the end of 19th century and spread rapidly. It was fairly common at one point across much of the UK, though in recent times seems to have declined.
