Our GP has just posted her annual warning about this pest. I was stung three or four years ago and still have an area of damaged skin as a result, so I pass on her warning as I do each year.
The Blandford Fly is prevalent in areas with water nearby, especially the banks of rivers. The females seek sources of a good blood meal before going out in the evening to mate. (Yes, we've all met the human equivalent!) They are low flyers and mostly attack legs and feet. May and June are the months when they are most active.
Wikipedia has a good entry on the Blandford Fly which I recommend reading.
