I could use lots of swear words, but in truth they are very efficient "recyclers" of anything made of meat that dies in the bush.
A fairly large ant with strong mandibles, and not afraid to use them on anything or anyone they perceive as a threat,
especially someone trying to remove bits of a fresh carcass they have "found".

...and they SWARM!
Fortunately they only bite and can't sting.

Close-up of the stag's eyes when I finally found him:

He had been dead for no more than an hour but was covered in the little buggers.
Tried repeatedly to brush them off for the photo but by the time I set the timer and jumped into frame they were back!
Did I mention they were tenacious?!

They have a strong smell of formic acid and need to be completely removed from the meat as soon as possible.
I also trim the meat a bit more than might otherwise be needed before cutting it up.
A single meat ant in the gob would definitely ruin the venison experience!
