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.
Why do Blandford flies bite?
It spends its larval stage in the weedbeds of slow flowing rivers and when the fly emerges, the female seeks a blood meal before mating. It usually bites the lower legs causing pain, itching and swelling. Scratching the irritated areas can lead to breaks in the skin, after which secondary infection may set in.
What do you do if you get bitten by a Blandford fly?
If you get bitten follow this PHE advice:
- Clean the bite area and dry gently.
- Don't scratch the bite, as this can lead to infection.
- Apply a cold compress or calamine lotion.
- Antihistamine creams are not recommended, as they can sometimes cause skin reactions.
- Cover large blisters with a dry dressing.
