Re my previous post, I don't need to return to see the adult. I stuck the larvae with its ball of vegetation in a jam jar, and hey presto!
Andy MusgroveNothris verbascella is a micro-moth, presumed extinct in Britain til rediscovered in 2024 nr Norwich by Dave Jones. Has only taken me 2 years to (literally) get on my bike and travel the 3 miles to see it. Larvae feed in the cruddy base of Hoary Mullein. Must return to see the adult in a few months.
