A female hoverfly of the genus Ferdinandea, probably Ferdinandea cuprea (Diptera: Syrphidae). One of the few UK hoverflies with dark markings on its wings (The only others I can think of at the moment are members of genus Volucella).

An ichneumon wasp (Hymenoptera: Ichneumonidae). I have no idea of genus nor species. As I have said before there are thousands of ichneumon wasps, and they can be very difficult to identify.

Yet another longhorn moth, this time a Nematopogon sp. (Lepidoptera: Adelidae). There are at least three Nematopogon species (N. metaxella, N. swammerdamella, N. schwarziellus) that look like this, so I won't attempt to take the identification any further.

A squat black female hoverfly, probably Pipiza sp., possibly Pipiza noctua (Diptera: Syrphidae) based on info here and here. Tends to stand with its wings partly open, instead of straight back over the abdomen.
