There are dozens of species of aphid common in the UK (and France), and most are partially host-specific. Regards, Nick Maclaren. 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: http://www.rhs.org.uk/advice/profile...upin_aphid.asp 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 ... Mary |
