thanks for plant!
As it could be expected (the weevil belongs in the nominate subgenus, nearly all species of which are associated with that family), it belongs in Brassicaceae. And I can tell more: it is Garlic Mustard (Alliaria petiolata). This plant is considered invasive, and for its control now 4 spp. of Ceutorhynchus are tested, but, it seems, none has been released yet (compare this summary)

I know all the four species mentioned, and can say, that yours is none of them. It probably is a native, opportunistic species.

Not Curculio
Curculio spp. are generally larger and often are brown colored. I think this is a different subfamily. Perhaps Boris will narrow it down.
