The Norfolk snout was always a rare moth in Britain. By the late 1960s, populations of this small beige moth with a distinctive protuberant “nose” had dwindled to just one site – a working quarry in north-west Norfolk.

Bad weather or possibly over-collecting by a few zealots meant that the moth, which has a 20mm wingspan, became extinct in Britain in 1971.

Now, after an absence of more than 50 years, the Norfolk snout (Nothris verbascella) has reappeared, close to where it was first discovered in 1853.
