Hi Arp
Thanks for the reply and the various links. Over the last two days I've learnt more about Ragwort and the insects it supports than I ever knew!

My quest was partially solved late last night when I found this company - Ragwort-UK Ltd.

That's another business idea down the drain!

Thanks for your help.

Howdy,

I'm certainly no expert on the matter, I just got into photographing insects on ragwort on request of an Internet-friend who runs a website aiming to clear up a lot of misunderstanding about ragwort. The English pages of her website are here - you may want to check the references page. Furthermore this discussion sums up some more English-language links. To get an idea of the anti-ragwort lobby have a look here. Also here is a page about control from the Surrey County Council. Hope it helps. Cheers, Arp

Hi p4b
I'm rearching biocontrol of ragwort using flea beetles and cinnabar laravae. I note your images of the species on this site and wonder if you had any specific detail or links you could supply me with. I would be grateful for any information.
