Green Tachinid Fly

From 2 years ago: Tachinid fly Gymnocheta viridis (Diptera: Tachinidae).  I had assumed that my first sighting of this species was this one in May 2010 but I recently came across these photos from 2009 which I had previously taken to be of Lucilia sp.

Dolichopodid Flies

Again from 2 years ago, a small fly with large antennae: probably a male Rhaphium sp. (Diptera: Dolichopodidae).  There are quite a few species of this genus on the UK checklist and in only a few do the males have these large antennae, one of these being Rhaphium calignosum.  The females have normal-sized antennae.

A few days later I caught another one in mid-flight:

Soldier Fly

From 2 years ago: a male soldier fly, probably a Beris chalybata (Diptera: Stratiomyidae).  The females of this species have a metallic green thorax, smaller eyes, and lack the swollen first tarsi on the hind legs.
