Widespread in England and Wales, rare in Scotland and Ireland.
Dryocoetes autographus (Ratzeburg)* - Naturalised. In dead and dying spruce Picea;
occasionally reported from other conifers. A well-established species in northern and
western Britain and spreading southwards. It first noted in GB in a plantation near
Scarborough in 1869.
Crypturgus subcribrosus Eggers – Naturalised. Dead and dying spruce Picea, in the galleries

Cryphalus asperatus (Gyllenhal)* - Naturalised. Develops in dead branches of spruce Picea.
Ernoporus caucasicus Lindemann - Nationally Scarce A. In bark of dead branches of lime,
both Tilia cordata and common T. vulgaris, but perhaps only in sites where former
has been present historically; branches range from 1.5cm to 5cm girth; often restricted
to one or small group of trees; a relict Wildwood species hanging on in areas of old
