japanese beetle

I have just found one of these pests on my rose shrub.  Munching away on the flower.  As it was the first one I have seen, should I be worried.?

Are you in the uk?

Hi, I live in Mid Wales, just inside the Shropshire border.  Mick.

Interesting- because from research it is not found in the UK-are you sure about indentification?-it is a major pest

I'm sure that I answered this - must be going mad!

There are a few in the UK - they've hitched a ride on imported Chinese acers.

They should be captured and reported, details here.

Link not working Alina-another oops

TRying again, Geoff - try here.

I was looking at these-that just seem confined to the usa

There seem to be a few in Europe and the UK now. It seems that the larvae are almost impossible to detect, and that's how they've got in. I'm not sure if we have breeding populations, though, or just odd stragglers.

I certainly hope it's the latter, as, as you say, they are a serious pest.

I think Mick needs to hopefully find it and take a picture for a positive id

could it not have been a chafer beetle?:

I checked the beetles identity with Wilkepedia.  The tan/brown hard type back  with the white zig-zag markings down each side.  Aprroximately   1 1/2" long.  I should have took a photo, before I got rid of it. 

Interestingly, I just found something that I thought was a Japanese Beetle also. Copper back; green metallic head. But not the tufts of white of the true JB ... so just a garden chafer. They're so similar, though. I gather JBs are actually chafers ... how closely are they and the garden chafer related? 

I think I have got japanese beetle on my roses, eating the petals.  Not sure what to do,just sprayed with rose clear, will catch one and take a picture.
