Emerald Invasion?

Anyone know what this beautiful bug is? A few google searches made me question whether it might be an Emerald Ash Borer - a nasty invasive species, but not one that's made it to the UK yet. However, that looks a quite different shape, particularly the back legs. Any ideas? 📷 Panasonic Lumix G9 + Lumix G Macro 30mm⁣ ⁣30mm, ISO 200, 1/800s at f/2.8
