Found the nasty beasties all over my roses at the weekend. Be warned! Am trying the soapy water trick, will let you know if it works. Too early for ladybirds ...
I thought they were Asian? 7 spots is European, 2 is rare and not sure where they're from, more than 7 is from Asia (or so I was led to believe). You can see loads of them if you walk around the east side of the front of Ally Pally in summer.
