Two late winter/early spring invertebrates

This little crab spider was lurking amongst a bunch of ripening ivy berries. When I disturbed it, the spider quickly disappeared amongst the berries. I posted this picture on Twitter a couple of weeks ago and @ivysuckle kindly identified it for me, as a running crab spider in the genus Philodromus

 There's a shield bug nymph crawling over this lunar landscape of apothecia of the lichen Xanthoria parietina. On Twitter, it was kindly identified for me by @AlanM24217579 as a second instar nymph of the forest bug aka red-legged shieldbug Pentatoma rufipes, apparently the only shieldbug species that overwinters in the nymphal stage.
