Harlequin ladybird

I found this little creature resting on a parsnip leaf (from one of last year's parsnips) at the allotment. I checked on the internet and found it to be a Harlequin. Should I have destroyed it, as I've heard they're pretty destructive?

It's so pretty against the parsnips! We call them Asian beetles here and they are quite annoying.

How cute! Great shot of it. :)

It looks like a lady bug in reverse. Nice shot!
