Norfolk status Scarce. Habitats where the foodplant occurs. Similar to Hornet Moth, but smaller with black head and shoulders. Adults rarely seen, as no pheromone lure available, but can be found by day in early mornings freshly emerged from Willow trunks. Overwinters twice as larva.
There are records from a wide scatter of locations around the county, and could occur wherever there are reasonably long established sallows or osiers.
