On recent sunny days, Dock bugs, both young and old, have been out basking in the sunshine.
I often find them on Bramble leaves and, occasionally, on the berries, though, according to the British Bugs website (which also has a helpful chart showing their different stages of development), they don’t eat these (not surprisingly, their main food source is Dock, as well as other plants in the Polygonaceae family).
Though their brown colour is quite obvious on Bramble leaves, that same non-descript colour and their ragged shape mean Dock bugs (Coreus marginatus) can be very inconspicuous. I only spotted the one below because it moved.
