I have a succulent (most likely Haworthiopsis attenuata) that is currently not looking so hot. I recently noticed a number of small brown scales growing on multiple leaves, that I think are some sort of pathogen (or at least are not part of the plant) for the following reasons:
- They don't appear to follow any sort of pattern like the white marks on the leaves.
- They are easily detachable with tweezers--I plucked two or three off as a test.
The best explanation I've found myself is that they're some sort of scale insects, but they seem really tiny. These are about the size of a Chia seed--only a few mm across. What are these, and as a bonus, how can I get rid of them? Photos are below:
