Cephenemyia stimulator Bot Fly in Roe Deer

[Jon P]

Had a phone call today with someone saying that large numbers of Roe Deer have recently died in the South of England from Cephenemyia stimulator bot flies in the nose.

Has anyone any evidence or information on this topic? .

Thank you in advance

I am assuming it is good news that no response has been received about this

I hadn't heard of this so had to look it up in my Boys Bumper Book of Parasites, which suggest it isn't an issue unless very heavy when they can suffocate the deer. The larvae get in when the female bot squirts them up the nose, then they migrate to the back of the throat. Might look a bit more for them Nose bot fly in UK

Thank you- I had not heard of it being a major issue, but person I was speaking to on phone was adamant that 1000 were dying of it in the UK.

was that a one off case ? Or a problem in numerous deer?

Two more to my knowledge in Surrey last year. One from me and one from a syndicate member. Warmer weather, more and more sheep in the area. These were all active healthy roe btw, none found dead.

Have you the video - or know someone that will let me have a copy for teaching. Can I use the photo please?

I'm used to "stuff" but that had me in the Ewwww category. No wonder suffocation is recognised.

It's not the sheep nasal bot - that's Oestrus ovis

I had one in the Surrey area this summer, not as infested as the picture you have but it was the first I had seen.

I must admit I’m not entomologist

We've seen a few in Hampshire over the last couple of years but otherwise healthy when shot

That must be terrible for the deer.
