The first segment of the antennae of the Black Vine Weevil (Otiorhynchus sulcatus) is longer than the maximum width of the pronotum (the broad area just behind the head).
In comparison with the similar looking Liophloeus tessulatus, the Black Vine Weevil has a comparitively small pronotum.
It also has pronounced 'spurs' on its femurs (thigh bone) whereas those on Liophloeus tessulatus are reduced to small lumps on the underside of the femurs.
