Eugnorisma depuncta is a pretty and rare moth that tends to be sporadic in its occurrence. It's commonly called the Plain Clay, yet it's more of a chestnut colour with dark brown streaks on the wing margins. This species does most well in deciduous woodland, scrub, heathland or other open habitat types. On rare occasions, they might visit gardens, too! They may be seen on the wing from July to September, but this is condition-dependent. These moths are much more rare in England and Wales, with most sightings occurring in Scotland.
