in german commly known as the "Silberne Grünrüssler, Silbriggrüne Laubholzrüssler or Goldgrüne Blattnager", I didn´t find any common name for them in english.
Phyllobius is a genus of weevils with lots of species, the green ones are very hard to tell from each other, all are widely present in Europe. They also are often confused with another genus of weevils, Polydrusus (which we also have in the garden).
They do look very similar, but the main difference is found around their snout: Both have a little cavity to rest their antennas, but it does look very different - Polydrusus`cavity is far more pronounced and in another direction - but also only visible in magnification, so in real life it is impossible to tell them apart. ;)
I found lots of them in the garden last weekend, so there will be some other shots upcoming.
Please respect my work.
