Hi Michael, It could be a Dung beetle we have lots of it around. It think the mites were eating it. It was stlll alive when I took the photo. Thanks, Peter
The mites are probably just hitching a ride on the beetle, i.e. they are phoretic rather than parasitic. If that is the case they will not be harming the beetle.

Thanks Kim. I looked at the extract of that article and it is a very potent and effective drug. It must effect native insects as well, is there any research that you know of on that. Peter
Native dung beetles are less common in cow and horse dung but their larvae would be killed by ivermectin. There is an alternative vermifuge in the same group that is less toxic to dung beetles but I can't recall the name Chemical alternatives to treatment of cattle with Ivermectin Chemical alternatives to treatment of cattle with Ivermectin
