Sloe Shield Bug (Dolycoris baccarum)
Sloe bush. They feed on both flowers earlier in the year and on fruits which are forming now.
Shield bugs are members of the sub-order heteroptera, and are 'bugs' in the true sense, hence the name Sloe Shield Bug.
Shield Bugs are so aptly named with the body casing definitely resembling a shield but they come in all shapes and sizes, but always looking a bit like they are carrying a shield on their back.
There are several different species, this is one of the most common.
