Liophloeus tessulatus (Weevil sp.)

Description:

Liophloeus tessulatus is a fairly common weevil (11 mm) that feeds on a wide range of common wild plants. As most weevils, it can't fly. This species can reproduce by parthenogenesis, meaning that, in some cases, females can reproduce by laying eggs without any action of males.
It can be distinguished from the very similar Black Vine Weevil (Otiorhynchus sulcutus) by the first segment of the antennae being shorter than the maximum width of the pronotum (the broad area just behind the head); the first segment of the antenna of the Black Vine Weevil is much longer. The Black Vine Weevil 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.
