Incredible Farm at Lumbutts has a photo which looks suspiciously like Greater Horntail Wasp (Giant Wood Wasp) Urocerus gigas. The NBN atlas shows no records for Calderdale. This wood boring saw fly attacks conifers and is native to North Africa. The insect is harmless despite its appearance.
The photo taken at Incredible Farm but on facebook page of Michael C Smith who works there. 6th August.

Anyone come across this insect before?
