Red hind head riddled with warble

[Aligillies54]

Not in deer, as already stated, different warble.

Good guide, thanks.

Warble under the skin Nasal bot fly in nasal passage or back of the throat, Warble does not seem to affect deer too much
but bot fly will bring their condition down severely, deer can often be seen sneezing and shaking their heads trying to get rid of them horrible things.

Thanks...I assume this eventually will end in a slow death? as surly she must be struggling to eat and also no young so would also assume that she couldn't carry young due to her decreasing health?

Heavy infestations such as you describe can be fatal,but mild infestations which are more normal while causing irration to the deer seldom. seem to have a long term effect on them.

The Nasal bot fly hatches her young inside her body then injects them into the nasal passage of a deer were they migrate to the back of the throat living and growing there until ready to leave their host, the deer ejects them by sneezing the grub then buries itself in the ground where it pupates before hatching into a f!y and the whole thing starts again

That's a layman's description , some of the vets on here may be able to provide a more scientific explanation.

I think so too.

Great detail, cheers! (Sounds bad!)

I think Warble may be notifiable, at least in cattle?

They are nasal bot fly larvae.
Warble fly is a notifiable disease in cattle only in Scotland as the England and Wales regulations were revoked from 1 April 2015.

It is notifiable in Scotland. Not in E and W since 2015.

Warble fly: how to spot and report the disease - GOV.UK

certianly used to dose cattle for it with an op based dressing. Bit like sheep dip.

...I should have read to the last page before posting.

I passed your photos to a vet and he came back with this he also stalks.

there are 2 species of deer nasal bots in the UK; Cephenemyiastimulator in roe deer and Cephenemyia auribarbis in reddeer. The literature suggests that these larvae can get pretty big, up to 20 –30mm in length, and can be fairly numerous in an individual, as the imagesshow. Again from the literature the adult flies appear to be large and hairy, reminiscent of bumble bees.

Warble in deer are not notifiable in Scotland - different species from those that infect cattle.

Thanks, and appreciate everyone's input on this.

Had same experience on Saturday. Shot hind, calf and follower. Calf was clear, follower had bot fly but the hinds throat was packed with them, literally pouring out when I removed the head. Absolutely horrendous.

If had seen this is think I would be sick.

Aye, it was the first time I had come across the bot fly myself and it's not a pleasant thing to see, but you just feel glad that you put the poor animal out of its misery.

Good call to take her.. Is it more prevalent in Scotland than England? I haven't seen them in Muntjacs..

Just looked them up - Deer botfly - Wikipedia

They really do look like bees! Or possibly very small Pokemon haha

There was also a link to a rather amusing article published by the NY Times back in 1937 stating that the deer botfly is the fastest insect known to mankind - They were apparently spotted flying at over 800mph!

To put that in context the speed of sound is 768mph and this claim has of course since been debunked, also for several (to me at least) amusing reasons.

To maintain a velocity of 800 miles per hour, the 0.3-gram fly would have had to consume more than 150% of its body weight in food every second;
The fly would have produced an audible sonic boom;
The supersonic fly would have been invisible to the naked eye; and
The impact trauma of such a fly colliding with a human body would resemble that of a gunshot wound.

Had this actually been found to be true it would have certainly added an additional element of danger to open hill stalking!!

These are nasal bot fly, not warble.

Warble are only found under the skin - usually along the back and spine.

Nasal bot fly are found in many grazing animals - not sure if either that or warble in excess are cause for carcass rejection - I doubt if either can create vectors for the transmission of any disease or toxins, though I doubt it. Each will certainly take the condition off deer.

Both pretty uncommon our side of the country, but more prevalent further west in my experience.

On my last day at the hinds I saw a poor looking hind with a strong herd and decided it needed to put out of its misery, and on initial inspection the coat was poor and it looked very skinny.
When I got home and skinned the beast I was surprised to see no sign of warble on the spine area. I then removed the head to inspect the nodes within the head and seen that the back of the throats and base of the brain was 'moving' with warble!! (See attached photos), first time I have seen this within the head and not a good sight at all, and really glad I decided it's time was up!
