It has been confirmed that what I thought was a Green Shieldbug coming out of its brown winter state, is the Gorse Shieldbug, Piezodorus lituratus. A couple of Box Bugs were active, along with lots of Bee Flies and a Carder bee, photographed with its proboscis deep in an Alkanet flower - the latter is an excellent insect plant, flowering early and attracting lots of bee species.
