Hi, I've found these under the leaves of my indoor palm, not sure if these are two type of pests or young/mature of the same one. Both the long brown ones and the small dark ones easily scraped off. Thought it might be scale however it looks different from the types of scale I've encountered so far (and no sap/stickiness).
The palm leaves have been turning yellow lately, I suspect it might be due to the pest? Otherwise suggestions welcome. Pics below. Thanks!
