I found this tiny Weevil on one of my Anthemis plants last summer.

The Rostrum is distinctly curved and the antennae elbowed.

The hindbody is pear-shaped.

Has anyone any ideas?

Family Apionidae; possibly Omphalapion hookeri (see http://www.mcclay...oSheet.pdf) who is looking for the right composite flower head to oviposit? However, the rostrum of this species might be shorter than that of your beetle. Search under Apionidae in http://www.koleop...index.html.

Hello!

I don't think, this is an Apionid. I have never seen a member of that family visiting blossoms for pollen. I am quite confident, that this is Anthonomus rubi from the Curculionidae, a frequent visitor of composite flowers.

Juergen is right. My knowledge of beetles stems from the times when Apionidae were no separate family but part of Curculionidae, and I thought that all the tiny ones with long rostrum would now constitute an own family. However, I meanwhile learned that the Apionids should have no elbowed antennae, so the depicted weevil who has clearly elbowed antennae is a Curculionid, and Anthonomus rubi is a good choice then.
