I guess they are aphids? - in my garden on foxglove stem which I cut down after flowers died. Aphids are in a distinctive eye-catching vertical line formation - all facing downwards. The largest specimens seem to have their bottoms leaning outwards from the stem (or maybe their rear legs are very long). Occasionally a lot of them would move or twitch all at the same time - very spooky, otherwise they are dead still. Watched them for a few minutes - didn't see any ants on the stem. But there are ants on the ground.
