Hazel Pot Beetle Cryptocephalus coryli (Linnaeus, 1758)

Many years ago, Cryptocephalus coryli was a widespread species across the southern counties of England, but it declined greatly during the last century to become one of the UK's rarest insects. It's decline is thought to have coincided with the reduction in coppicing. In the south of the UK, it occurred on hazel growing along woodland edges, rides and hedgerows, but in the north preferred a heathland habitat with Birch scrub or young trees.

Historically, Sherwood Forest was always regarded as being good for C. coryli by collectors in the early 1900's, when over a dozen adults could be taken on each visit to this locality, with the beetles either being beaten or picked from young Birch and Oak during June. C. coryli was rediscovered at Sherwood Forest CP in 2008, the first time it had reliably been found there since the 1930's. There are also records from Clumber Park in 2014 (Binding, A. and Binding, A,) and 2023 (Brownley, N. and Brownley, S.).
