I've only seen them on lupins.

Essentially, yes. There are dozens of species of aphid common in
the UK (and France), and most are partially host-specific.

I remember informally seeing mention of "lupin aphids" and you
certainly tend to see them on most lupin plants sooner or later and
they are distinctive through sheer size but here is the lowdown as
found by google:

But that site says: "This aphid is native to North America and was first
detected in England in 1981"

Well, sorry, but the ones in my garden were in the 1960s. We moved into this
house in 1964 and lupins were already in the garden. I saw the aphids
shortly after and pulled up the plants, never had them (lupins) since.

Perhaps it was only defined as a different aphid from the ones already here
in 1981 but the ones on our lupins were so distinctive that they were
memorable. My mother was a great gardener and always had lupins, I never saw
the aphids on hers but that was before we moved here.

I'm not claiming to be a First ...
