What to do about harlequin ladybird larvae?

[Cookiecooker]

Dd(3) was very excited by the new "weird beastie bug" she found this morning when watering her potato plants. I had no idea what they were...a quick Google and it would appear they are harlequin ladybird larvae. So, other than reporting I've found them to the harlequin survey is there anything else I can/should do? We're quite new at this gardening thing so haven't a clue!!

They are every where, I'm surprised anyone is bothering to keep a survey going these days. I'd just leave well alone, presumably they will still eat your aphids?

We are surprising aphid free...so i presume so!
