Small Metallic Dark Blue Beetle - Chrysolina of some sort maybe?

[seafisher]

This coupling couple was snapped on some new Hazel growth today - they look a lot like Green Dock Beetles (about 8mm maybe) but are dark metallic blue (almost black) and the very swollen female (with eggs) has a yellow abdomen - any ideas?

Maybe Chrysolina of some description but I'm fairly new to Beetle ID

Any help would be great.

Thanks

Anyone any idea what these are?

I know I'm being a bit of pain but they'll be gone soon and it would be nice to know what they are before the eggs and little uns turn up.

There's a few metallic blue-ish. The one I'm most use to is the Alder Leaf Beetle (Agelastica alni)

Thanks for that bugbrother, just had a look through the 'net' and the description and pictures match exactly

Thanks loads
