Good or Bad: Common Red Soldier Beetle

I recently planted a new border and my astrantia majors have been invested with this little red beetle. They spent most time on the astrantia but have now moved on to my Jacobs ladder and hydrangea. A bit of research suggests that these are positive contributors, however it appears that they literally suck the life out of the plants. Does anybody have any advice on this matter?

Thank you very much in advance for your support!
