What I think is a carnation tortix moth, Cacoecimorpha pronubana (Lepidoptera: Tortricidae). It took me quite a while to identify this, but I eventually matched the rather faint downward-pointing arrow marking on its back with one of the images on the page linked to above.

A pair of Sicus ferrugineus (Diptera: Conopidae) mating on birds-foot trefoil, (Lotus corniculatus). Heads that look like they have been constructed from a pineapple chunk and two chestnuts.

This rather spectacular fly is a male Phasia hemiptera (Diptera: Tachinidae). I twice saw females of this species last summer: once in Reading and once in Barnard Castle, but this is my first male. As the name suggests, their larvae are thought to parasitise various hemipteran bugs.

A pair of Conopid flies, probably Conops quadrifasciatus (Diptera: Conopidae). See here for my reasons for excluding the other Conops species that are found in the UK.
