Local in pine woodland throughout much of England and Scotland. In Hampshire the majority of records are from the south of the county, but apparently increasing, or perhaps increasingly recorded, with no less than nine records in 2007. Not recorded from the Isle of Wight to date. Wingspan 8-10 mm. A small and nondescript pale grey moth, very similar to O. piniariella, from which separable only by dissection of the genitalia. Larva mines needles of Scots Pine, living between needles spun together with silk.
