Thanks for your id dhobern

Thanks for your id dhobern which has taken me to similar images and think it may be an Oak Weevil. There were no Chestnuts present but a lot of very fine specimen Cork Oak trees. The weevils appear to be very similar. Any other comments would be appreciated.

Chestnut Weevil

also feeds on oaks. So the lack of chestnuts should not be taken as negative for the identification.
How long is the body in terms of absolute size? C. glandium is about 6 mm and C. elephas 9 mm so that should help you to decide.

Unfortunately I don't remember from 2years ago and didn't take any notes at the time.

Hi Geff. As you know I posted

Hi Geff. As you know I posted a photo of a similar weevil recently. I did a bit of digging and found this page which explains the difference between Curculio glandium (Acorn Weevil) and Curculio nucum (Hazelnut or just plain Nut Weevil) http://en.m.wikipedia.org/wiki/Curculio_nucum. Looking at your photos I think this maybe C nucum, but I'm not at all sure. I've posted my photo on the Facebook "Friends of Coleoptera at the Natural History Museum (Entomology department)" page at https://www.facebook.com/groups/38603112572/ but have yet to get a response. I don't hold out much hope given the lack of clarity in my shot. I think your photos give a much better chance of a definite ID than mine Cheers, Martin

Hi Martin, Thanks for the

Hi Martin, Thanks for the interest and the research. I am not on Facebook so am unable to look at your link. However, the link to wikepedia shows a comparison between two antennae and I believe my photo to be more like C. glandium with pale rings around the tip area, so I am going to stay with Acorn Weevil for my i.d.
I would be interested to hear if you get a reply from the "Friends"
