Eurydema oleracea

After Mrs Catspaw's discovery the other day, this morning it was my turn to discover the nymph of a different Shield Bug in our back garden, this one feasting on the flowers of some Broad-Leaved Thyme (Thymus pulegioides).

Online searching suggests that today's nymph the final instar (juvenile form) of the Brassica Shieldbug (Eurydema oleracea), although the closely related (but much rarer) Scarlet Shieldbug (Eurydema dominulus) ('with just a few recent records from parts of Kent and Sussex') is also a possibility.
