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. |
