Hi, has anyone found an answer? I have these too. I know they are not perlite or fertilizer as they are showing up in plants that do not have these additives, like plants I have growing in moss. They have liquid inside, range from grey to white in color, do not dissolve in water, have irregular shapes and no smell, sometimes are buried in the soil and sometimes left right on top.
I wonder if this is an insect egg meant to imitate perlite in looks and function which is pretty smart. I have no other pests around my plants except thos every small flies occasionally, only tiny black ones that buzz about and none on any leaves that I can find. Would love to know if they hatched or if anyone knows more about these weird pellets!
