Large, ~15mm, Dark Bug with Feathery Antennae

Observation - Large, ~15mm, Dark Bug with Feathery Antennae - UK and Ireland. Description: Landed on this forget-me-not with a great whirring of wings. The thorax is pale brown, mottled darker and I think the abdomen was dark but unfortunately it didn't stay long enough for me to get a photograph from the back.
