Yorkshire Status: Scarce and local resident.

This species was formerly much more common in the county. In 1883 Porritt noted "distributed throughout the county and generally abundant". How times have changed. Dutch elm disease is certainly a major factor in its demise as it seems to like elms of a decent size. Scrubby hedgerow elms are not of its liking. It seems to have disappeared from many former haunts and is mainly encountered in VC62 though it occasionally pops up in other areas such as one at Oughtibridge in VC63 in 2023. It appears to prefer wych elm to English elm.

Sutton & Beaumont, 1989: This species has declined in numbers since the spread of Dutch elm disease but its distribution has not changed a great deal since 1970. It is still widely distributed and fairly frequently found in hillside and valley woods with wych elm in vice-counties 62 to 64. However, there are only single records from VC61 (Flamborough, 23.6.1974, SCM) and south VC65 (Tanfield, Flint, 1972a). It has been suggested it may be able to feed on beech or hazel as an alternative to elm (AMRH pers. comm.).
