Deporaus betulae
A black weevil often found on Birch, hence the latin name betulae. There are several similar looking species, making ID 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. The lower two photos show a female in the process of cutting through a Birch leaf at Sherwood Forest CP in May 2010.
