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.
