These beetles were about 1/3 the size of the Greater St John's beetle (4705570) that I posted so I thought they might be the lesser St John's wort beetle - Chrysolina hyperici.

@galah681 Thanks. I'm not aware of this other species and it is not listed in the species list on CNM. I'll leave it to more expert persons.
