There is an rspb forum on the rspb commuinty page, i'm on there and there is always people on it, they can help you identify practically anything, iv asked from bugs to birds and everything inbetween. I am on the rspb site everyday mon-fri.
heres the link:
Under the wildlife tab there is a many page forums on different subjects from identifying something, asking an expert a question, lastest spottings, photos etc
Under Chat tab there are forum pages for books, gear, Helloo (for newbies to introduce themselves) polls & quizzes, art bit, as well as "tea room" to generally talk about anything
Everyone on there is very helpful and friendly, and as like on here there are many knowledgeable people who can give you advice and are surly going to have the answer for you're question
Both this site and the rspb one are really good as they are both very active, you never have to wait long for an answer or a helpinghand to find someone who could help you
