You were pretty close with "yeast", but they are laboulbeniales fungi of the Class Laboulbeniomycetes. They are quite common on dung beetles from around the world, and also occur on a wide variety of other beetles. A five volume work on the group was published by Thaxter from 1896-1931, but I think the group has been neglected by Mycologists over the last few decades . . . or perhaps half century!

My colleague, Wes Watson, has a project with Onthophagus taurus. A number of the adult beetles he’s recovering are speckled with yellow spots. Closer examination reveals what appears to be yeast(?) in the spots. Have others made a similar observations on beetles? Photos are attached.
Any clue as to what these are?
If you can help Wes out, I know he would appreciate it. Please contact Wes directly at [log in to unmask]
