Deporaus betulae (Linnaeus, 1758)
A black weevil often found on Birch, hence the scientific name betulae. There are several similar looking species, making identification potentially tricky. This is another small species, which was found on Sherwood Heath in early May 2009, but we have also found this beetle at Sherwood Forest CP and on Hazel at Lound Wood, Eakring. Length 5mm. The females cut most of the way through a leaf, producing an inverted cone, in which an egg is laid (see lower photograph). The lower two photos show a female in the process of cutting through a Birch leaf at Sherwood Forest CP in May 2010.
