The Blandford Fly (sometimes called blackfly) is a small 2-3mm insect usually found in East Anglia, Oxfordshire and Dorset. Blandford Fly bites are most common during May and June. They often occur on the legs and can be very painful. The effects of the bites on humans range from small blisters to large (up to 22cm diameter) haemorrhagic lesions, which can produce intensely painful stabbing sensations. The saliva of the fly, which passes into the wound, often causes severe irritation, pain, swelling and blistering.
