actually having read a bit about ladybirds, don't release them onto the lupins, keep them caged and fed, allow them to have sexy time then put the larvae on the lupins, the larvae have the advantage of a) they won't fly onto your neighbours lupins immediately you release them b) they are the main feeding stage and are voracious eaters
a ladybird can produce 150 eggs per day, a box of 100 would see your whole neighbourhood right
