My lupins have been invaded by grey flying torpedo shaped bugs, with voracious appetites--they are demolishing my many lupins. Does anyone know what they are and how they can be controlled for another year? I put a glove on and started squishing, as they are slow movers. Any info would be great. I need to get a bug book! Thanks

It sounds like you've got Lupin Aphids. The following page is from the Royal Horticultural Society in England but the information is good here too. Blasting them with water can provide temporary relief but you need to get out the chemicals to have much of an impact I'm afraid.

I check my lupins regularly for aphids. I noticed these on mine and dusted with rotenone. Haven't seen them since.

Thanks, Susan and Jo-Anne, for your answers. I have looked up the UK address as well as some others.The description of the other aphids doesn't be the same as these flying monsters, but perhaps they were more aophid-like when younger. I will need to keep watch next year.I am so hesitant to use an insecticide, as the bees are so busy in all the flowers at this time of year.I will also cut these plants down and clean up, and that might help.

I was hoping the title meant that the lupins were invading! I was excited about that prospect. But I do have a question. When should I gather lupin seeds to save for next year or should I just plant them now? When are they 'ripe'?

Thanks Diane

I wouldn't mind an invasion of lupins either! I grow a lot from seed and keep adding them to the garden... The seed pods on my plants aren't ripe just yet. They need to lose that fuzzyness and turn dark brow/black and get quite hard. Then I pick them and put them in a brown baper bag to dry further. The pods will curl and open as they dry and expel some of the seeds quite exposively when they do (If they're not in a bag but loose somewhere, you'll start finding seeds all over the room....) Sometime in September I harvest all the seeds from the pods and store them in the crisper in the fridge for the winter. In Mid March or so, I mix damp peat with sand (~50/50), add some seeds to it and put it all in ziploc bags in the crisper again. In 6-8 weeks you should see seed roots starting to appear. Once the roots are visable, pot up the seeds into peat pots in seed starting mix and place under lights. When I plant the seedlings, I just tear off the tops of the peat pots so no peat pot edges appear above the soil and plant the seedlings, pot and all, in the garden - they have tap roots and don't like being disturbed. They don't flower in June in the first year but will in September often. Any leftover seeds I just scatter on the ground in the garden and the crisper storage is enough cold treatment that many of them will germinate in the garden without any further effort - as will seeds scattered in the garden in the fall.

Sorry for the long-winded reply but I do love growing lupins...!
