Golden-bloomed Grey Longhorn - Agapanthia villosoviridescens
The only other time I saw one of these was three years ago, also in our garden, on a leaf of a currant bush.
This one was on umbellifer leaves in our garden. I could not get head-on shots before it tumbled into the mass of stalks. I searched but could not find it.
Shortly afterwards, I thought I had found it again, a few paces away. To cut a long story short, this was a second one (damaged tip of elytron) and I found the other one again back in the first position and, finally, this second one, further away. Both flew at various times and it was only with the second one, at the second encounter with it, that I got the elusive head-on views.
