The weevil cometh

Saturday was a lovely day in the land of Kent so the Stetoda family set out 'en mass' in the Wolsey for the clear blue seas and palm fringed coves of Deal. While poking about and generally annoying the insect population of the area I noticed this weevil behaving strangely. At first sight it appeared to be just resting the day away under the eaves of a beach hut. Then I noticed that it's head was moving, was it feeding on something in the spider cocoon? it definitely pushed further in to it as I watched. I am not familiar with the feeding habits of weevils but this seemed unusual. Is this a normal Vine Weevil or have I misidentified it ?

    Re: The weevil cometh
    I do not think it is the Vine Weevil (Otiorhynchus sulcatus F.), since it should have visible keels and grooves (sulcatus = grooved) on the elytra (cf: here).
    Instead, it might be the much less common Otiorhynchus auropunctatus Gyllenhal, 1834... here a fairly good picture.

        mmmhm... you're right

        Hence, it might be Otiorhynchus aurifer Boheman 1843, this should be present in England...

        Here you can see a series of pictures of an Italian specimen, though it seems to me larger than 10 mm...

            Curculionoidea are usually phytophagous... but they are so many species that I do not feel like saying whether and which different behaviours exist.

            Here you can read the most recent general paper about this group I known, Different alimentary behaviours are mentioned.
