Heterocerus fenestratus (Thunberg, 1784) 
A small (4mm) dull looking beetle, which despite it's small size is distinctively shaped and easily recognisable as being a Heterocerus when seen. There are of course a number of very similar species, but most can be ruled out in Nottinghamshire as they have a largely coastal distribution. Heterocerus fenestratus is little recorded in Nottinghamshire (based on the number of records available) and is found at the muddy margins of ponds and lakes etc. But it occasionally turns up at MV light traps, such as the two pictured below did turning up on warm, humid nights in July 2021.
