Image #5 is of green aphids, not greenflies. Wingless females give birth to female clones, which is why you see five mature female aphids, and a brood of immature females.
Thank you all for the helpful comments. I will return to the Green Aphids today and watch for longer as Bill suggests. I was surprised to see them in October. Also yesterday I found this Shield bug instar which I thought was a bit late in the Season - perhaps our hot Autumn is affecting things, certainly there are less birds around than normal.
