    Hi Remo

    The first picture (011) is one of the common, smaller hoverflies; Melanostoma scalare.  The fact the eyes aren't touching shows its a female and the white "dust" patches on the face are useful in distinguishing this species.  We now think that "M.scalare" is more than one species, the NHM is doing some DNA analysis to answer this question.

    Pictures 008 and 004 are Muscid-like flies, so related to the archetypal "house fly", but with nearly 300 UK species this is a fairly diverse group with a range of life-strategies.

    The last picture (001) is a classic bluebottle.  A member of the Calliphoridae which includes the greenbottles and cluster flies.  This is a much smaller family in Britain that's just shy of 40 species.  There are a couple of common and widespread bluebottles, a view of the face and "jowls" is the best way to tell them apart.

        Hoverflies are a good group to tackle if you are getting into flies, there is an active recording scheme, good keys and a photo-guide to the commoner species is due out later this year.  Bluebottles not too bad but other Calliphorids and the Muscids need a bit more care. I waited a few years before looking at those groups!

            These look like Syrphus ribesii (004) and Eristalis pertinax (001 & 003).  However, there are similar looking hoverflies to these species; a clearer view of the leg colouring would help to confirm the ID in both cases.

            Well I'm confused by this spider.

                Yes, this is a wolf spider, a Pardosa almost certainly. That's as far as I (and probably anyone) can get from a photo because there are lots of species and they're not especially distinctive.
