@KylieWaldon I would suggest that this is likely to be a Lipotriches sp. or Nomia sp. but given we can’t confirm the details I’d say it’d be unlikely to have an accurate confirmation on this one sorry🥲
These are galls, which are cancerous like growths induced by fungi or a range of insects, to create conditions in which their larvae or spores can grow. Not sure whether these galls have been created by a chalcid wasp or coccid scale bug.
