Several of these small green Mirid bugs turned up on newly emerging globe thistle flowers. They are common bugs all over UK, but these are the first of this species I found in the garden. This species prefers low vegetation such as nettles and thistles, and is identified by its black & green colour and, if you look closely enough, black stripes on the hind femur. The other insect is also a bug, but in this case a nymph of Green Shield Bug (Palomena prasina), which I found in my mini wild-flower meadow.
