Another non-lep at the moth trap last night. Curculio weevils are a bit tricky but with the aid of a bit of magnification you can see the shape of the segments on the antennae confirming the ID. The inset picture below comes from here and shows the Acorn Weevil (C. glandium) on the left and this species on the right.
