Shining Oak Tortrix Pammene splendidulana
Formerly given the vernacular name Drab Oak Piercer, though "drab" seems a little unfair.
This is Nationally Scarce species that has only previously been recorded in Norfolk in 1874, 1994, 2015 and 2026 (source: Norfolk Moths).
I found this by sweeping birch beneath Pedunculate Oak at the edge of a small woodland. The identification seems to be fairly straightforward although there appears to be some variation in the shape and size of the dark discal spot and the presence or absence of the two smaller dark subterminal dots. The white dorsal blotch is also variable, appearing much more obvious in some individuals than on this one. It isn't apparent from my photos but the curved grey fascia through the forewings are shiny and reflective in life. Given its scarcity I thought it worth dissecting just to eliminate any possible doubt.
