Scale like bump. May be an egg?

[Girl_With_An_Orchid]

Hello. I’ve been seeing these things (see pic) show up on my plants for a while now. It seems to be one plant at a time. They look like some kind of scale or shell. The smaller ones are light in color and as the get bigger they get darker in color with some kind of stripyness to them. They can be removed easily with light pressure. There is some kind of insect guts-like goo inside. There is no damage to the leaves or flowers from what I can see. Not under the spots/ scales or around. They do seem to grow but I have never seen anything come out. This pic is the first time I’ve seen them on flowers. Generally it’s been the leaves. Anyone know what these are and how to get rid of them permanently?
