help to identify metalic green caterpillar please

[heathermary]

can anyone help me to indentify this little caterpillar, at least I think it is a caterpillar because of the way it walked along, which i got on a short clip of film. Happily gardening away, and spotted it, at first I thought it was a beetle because of the colour and shape, but looking closer it walked like a caterpillar and seemed to have a soft ish back. It then curled up in a ball in the rocky wall, in the daytime. I took it on the 24th may, in the cornwall area.

Have a better profile picture, but you cant really see the colour very well on it, but it does show these wicked looking pincer type mouth parts.

Any help appreciated, thanks

What an odd thing and fascinating looking creature!.
Personally I dont think it is a caterpillar...as for what it is/will become I am intrigued.Maybe a beetle larvae?

There was no strange lights in the sky before you saw him?

It may be the larva of a Bloody-nosed Beetle.

I would second this

They feed on Goosegrass and other Bedstraws
