Weevils

Thanks Agnes! I just had a moment to look in depth at the information that you provided. I am in agreement. Thank you so much for your efforts! I have updated the scientific name

I am positive now. An identification key separating green Phyllobius and Polydrusus weevils is by the position of the antennal insertion on the head. In all Phyllobius sp, the insertion point is viewable from above, whilst not visible from above in Polydrusus sp. - http://www.eakringbirds.com/eakringbirds.... Looking at your spotting, the antennal insertion is more on the side, which is more obvious in the larger female weevil in this spotting. Also, here's a matching image also taken from Costa Rica - http://www.flickr.com/photos/40300661@N0....

Thanks Agnes! If you are positive that it is the Polydrusus sp. I will update the scientific name. I couldn't differentiate between any of them as they all look similar. It is likely that one could only tell the difference with dissection. It is paramount that we get this right!!

Yes, they look alike indeed. :) But I could not find any mention of Phyllobius sp. distribution in Costa Rica..

Could also be Phyllobius

Thanks Agnes. I think you are right on the mark.

Possibly Polydrusus sp. (Curculionidae, Entiminae), but I am not sure.

any suggestions?
