Yorkshire Status: Rare and very local resident.

This declining species is still present in the south-east of the county. Most records come from the Doncaster area and are often of the distinctive large larva, though adults do occasionally come to light. A record of a larva from Blacktoft Sands in 2023 is a good distance away from the usual area and is rather encouraging. Willows were planted about 40 years ago at this site. Larvae over-winter for three or four years in the heartwood of various trees, particularly willows and poplars, usually in low-lying or damp habitats.


Sutton & Beaumont, 1989: This species is now very scarce in Yorkshire. There are only records from two widely separated areas, although no post 1960 records are shown for Yorkshire on map 3 in MBGBI 2. The species seem to need old poplar or pollarded willow (B MacNulty, pers. comm.) which may now be rare due modern farming practices.
