CAN ANYONE IDENTIFY THIS FLY?
GRAEME STROUD WRITES: Does anyone know what type of fly this is? I don’t remember seeing one before, certainly not all this year, but at lunchtime today I saw two. They are elongated, about 15mm long, with a metallic gold thorax. They can hover like a hoverfly, and the abdomen shows metallic purplish-blue, although that is not noticeable when at rest.
