So on receiving images of several caterpillars on supermarket mint from Anneli in West Berkshire I was naturally suspicious but also curious.
A leg count showed two prolegs missing suggesting they were likely to be moths of the Plusiinae family.
Silver Y was a possibility but it was difficult to see certain diagnostic features from the photos
Sixteen days later I received an excited email from her with images of’ an amazing moth’
A glance at the images and I understood her excitement.
Two Slender Burnished Brass had emerged!
Slender Burnished Brass are rare migrants to the British Isles from southern Europe and Africa where they are considered a crop pest.
Despite occasional ones arriving most years they are unable to withstand our cold winters
The equally impressive Burnished Brass is a common resident of the British Isles.
My thanks go to Anneli for sharing her photos and rearing them through.
