Species account (old)
In Robson's time and up to about 1935 this species was regularly recorded as larvae on the juniper at Blackhall Rocks on the Durham coast [...] The juniper at the Blackhall site is now reduced to one small, almost moribund specimen which no longer produces records of larvae of the above species. The only recent record is of larvae on the juniper in the Waskerley area in the 1950's, by F. W. Gardner. It has not been found on the Upper Teesdale junipers, in spite of diligent searches during recent years.
