Looks like a Rose Chafer, Cetonia aurata. If you’re not in the UK/EU it could be a similar species. Wikip. say North American rose chafer, Macrodactylus subspinosus for the US.

It looks like cornflower and knapweed seeds of UK species, so I’d expect a relative native to that region. Sow it, they’ve got a good rate of germination so you could find out that way :)
