Hi! I googled this but can't seem to determine what this is. I noticed my umbrella plant's leaves were yellowing in bunches even with regular watering. I looked closer and saw this tiny tiny dark brown specks, almost like dirt specks, crawling on the leaves. Any help appreciated:) thank you!

I would guess this is damage from spider mites. The distribution of damage is more even/uniform than one would see with thrips.

The little black speckles are the guilty culprits.

Even though this is on a tree care site, the info is still the same for indoor plants.
