    VC55 Status

    Although the Bagworth Heath Woods record of 7th June 2013 is only the second record for Leicestershire and Rutland, there were about 50 individuals found at that time. It would seem therefore that the weevil is present in numbers in our area and can be frequent when conditions are right for it. There were only 2 VC55 records for this species up to March 2015.
