This beetle is I think a member of the Aderidae if i have keyed it out correctly from the AIDGAP guide to beetle families. The legs from front to back seem to have the following number of tarsi respectively 4:4:3 and it has very thread like antennae and distinctive dark bands on the femurs. I have looked at the excellent Watford Coleoptera group website but cannot see anything quite like it. Any coleopterists out there able to help?
In case your coleopterist doesn't materialise it might be worth checking out Oedemera species. See -
Thank you for the link and by looking at several other websites I think it is Oedemera femoralis but i will try to get specific confirmation and find out a bit about its ecology. The tarsal segments that i counted 4:4:3 should be 5:5:4 for this genus and family, but are very hard to see clearly.
If i get absolute confirmation i will let you know.
But, i am intrigued how you found a picture on a french website so quickly!!?
Dave, I found it by looking first at this page, which I have bookmarked,
I found it in the first family I investigated. Then I just searched for a better picture in Google Images.
Thanks for your help and great websites you linked for me. I have also sent my photograph to the Watford Coleoptera group who have a great website and they kindly confirmed that it is Oedemera femoralis which is a nationally notable beetle flying at dusk and during the night fom March through to October and is particularly associated with the flowers of sallow and ivy on which it feeds.
Glad to help. Yes, I have come across the WCG website - it's good.
