Shield bug - NOT amateur radio

When the frosts and winds come we'll soon forget that it is mid-October and it was so warm that we had a cup of tea in the garden in our shirt sleeves.

This weekend some places in the UK could reach 24 deg C, which is very high for mid-October. Strangely, many trees are losing their leaves, which is early.

Whilst cutting the grass I came across this beetle. I think it is a shield bug. It was about 1cm long and mainly green. It flew off shortly after this photo.
