Oxford NHS Foundation report that their Minor Injury Units have seen a significant increase in patients with bites from the Blandford fly – a bloodsucking black fly, 2 to 3mm in size, which gives a particularly nasty and painful bite. The Blandford Fly (Simulium posticatum) is usually found near slow-flowing rivers and lakes – meaning both our sites are likely to have them this summer.

One of our members recently sent in this report:

On Tuesday evening, I was doing some watering and had just filled a couple of cans when I felt an insect bite my arm. I looked down and saw a small [about 2mm long] insect. In my shed, I keep a bottle of Dettol™ and I swabbed the bite area. We left for home shortly after and I took another look at the bite. I could see something black inside. I swabbed it again with Dettol™ and investigated with my jeweler’s eyepiece and a needle. I managed to fish out what I presume was the part of the insect which was after my blood. It was about 1mm long. Again, a Dettol™ swab was used. Before going to bed, I applied some hydrocortisone cream and covered it with a plaster.

I had a suspicion I had been bitten by a Blandford Fly and a Google search seemed to indicate this possibility. If so, the results can be mild or quite serious but there appears to be no bad reaction today.

If it was indeed the Blandford Fly that bit me, then I would not be the first one on the allotment to be attacked. My advice is do not take chances and swab the bite as soon as possible with Dettol™ or similar. See if there is something to fish out and use a magnifier and needle, carefully. As these beasts like water, be careful near the water troughs.

Your Secretary has also been the unfortunate recipient of one of these bites and can confirm they are really quite painful. NHS advice on how to treat these bites can be found here.
