weevil - Rhopalapion longirostre
Description:

This weevil is very small but quite distinctive, with yellow legs and a very long snout. It was found to be breeding in the UK for the first time in 2006, in London, and a few days after that I found the second UK colony in my garden in Bucks. The colony persisted in 2007 but couldn't find it at all in 2008. It feeds on Hollyhock.

identification

It was sort of pre-identified - Richard Jones, who found the London specimens of longirostre, put a note out on the British-beetles egroup (a Yahoo group) requesting that people search their hollyhocks for inordinately long-snouted weevils. By chance I had been checking my hollyhocks a few days before and had recorded two other species of weevil, as one does, and replied to Richard to say that longirostre wasn't here, but having done that I decided to have one last check and this time it was immediately obvious.

It often seems to happen that one doesn't see species until one has been shown them or told to look for them. As far as I know no-one else has found UK longirostre outside London and Great Kimble.

Still present in East Dulwich every year since, and a few other localities a few kilometres away.

Good to know it survives in the UK, I miss seeing it in my garden!

Has the name changed perhaps? Or is it misidentified (I have agreed)

I'm confident of the identification for this one! Although sadly it is now extinct in my garden. I think it is still resident in parts of London.

There is no national recording scheme for weevils so the records on NBN are rather thin on the ground.
