Phyllobius maculicornis
It took me a while to get to grips with some of the differences between the Phyllobius species, particularly between argentatus and maculicornis (I still find judging the eye size unreliable). I've reidentified a few and binned a few old records where I have neither a specimen nor a good enough quality photo.
This was potted off Field Maple.

One of these was netted in flight below Pedunculate Oak and the other was potted off Hawthorn. The first three photos show one individual and the other two photos show the other.

These were found in copulation on Hawthorn and I originally identified them as Phyllobius argentatus, though noted that one had less obvious suberect setae on the elytra. Given that both show dark tips to the scape and dark antennal clubs (especially the male) and both show the elytral pattern of maculicornis, I think these must be maculicornis not argentatus.

This is another one that I initially called argentatus but on review I think it has to be maculicornis. So far as I am aware the spermatheca isn't useful, but I've included the photo in case it proves to be.
Phyllobius maculicornis, St Mary's churchyard, North Elmham (Norfolk, UK), 27th May 2021
This was on Wild Cherry and again I initially identified it as argentatus but on review I think it must be maculicornis.
