What pest is this on my cotyledon tomentosa?

[Kcoles8]

Hi there!

I recently purchased a cotyledon tomentosa, which quite quickly started showing signs of having some kind of pest infestation. I’m not quite sure what kind of pest this is or how to treat it, so I was hoping that someone on here could help! I’ve attached some photos below!

Thanks for your time!

The first picture looks like eggs, possibly of a caterpillar. No idea what species. Look really carefully and you may find caterpillars or other bugs.
Picking off leaves with eggs and spraying with soapy water are non-toxic ways of trying to sort this.

Your first image does seem to show insect eggs. Most likely, the insects have already hatched and dispersed. Images 2 and 3 do show something that may not be related. No 3 indicates feeding damage by either by a beetle, caterpillar or snail, while image 2 could either be an internal feeder, e.g. a leaf miner, which could be either a fly or a small moth larva, or it may indicate the presence of a pathogen. You could go ahead and cut that leaf open with a sharp tool or a pointy one like a needle and check, if something is inside feeding. The small larvae, if present, are usually of an off-white color or may be yellowish.
Once you know who the enemy is, you can treat the plant accordingly.
