Diaperis boleti (Linnaeus, 1758) 
A beetle making steady progress north through the UK, with most records from south-eastern counties. There are just two known records of this beetle from Nottinghamshire, with a gap of over 130 years between the two. Historically, Diaperis boleti was recorded from Sherwood Forest in 1891, but then not seen again in Nottinghamshire until July 2025, when found at Kirkby-in-Ashfield by Nick and Samantha Brownley.

The couple then found it close to the Major Oak (two) in Sherwood Forest CP a week or so later, before over eight adults were found in old, dry Birch Polypore Piptosporus betulinus at the former staff entrance to the old Sherwood Forest visitor centre on July 28th (Pendleton, T.A.) before being recorded at Bevercotes Pit Wood and Clumber Park in August 2025 (Brownley, N. and Brownley, S. It is associated with and will often be found on the underside, or inside the fruiting body, especially those open to the sun.
