I've got an infestation of bugs and don't what they are. They are falling from a fir tree in my garden onto my raspberries. They look small, but larger than an aphid, spider like, brown grey in colour with ???two black spots on their behinds. There is a honeydew like substance (might not be connected) but no sign of webbing like with red spider mite. There are thousands and I've tried organic bug spray but there are too many of them. I'm very concerned that they will spread round the garden onto my other crops and into the greenhouse. Described them to guy at allotments and he had no idea. Can anyone help, please?
Thanks
Maybe some sort of aphid that particularly likes conifers. There is a group called Cinara, with many different types. Maybe this one? :

If it is, they tend to stay on the plant they prefer, i.e. conifers.
Thanks for the lead, looks more like it!
