Lily beetle - another update. Lilioceris lilii is a tenacious little insect and is rather resistant to spraying. This is because the larvae cover themselves in their copious liquid excrement, exuded from the anus which is on the top of their back. As well as disguising them as mush, and probably making them less than tasty, the goo also serves as a barrier to insecticide. A systemic insecticide will poison them from the inside, but as many people have said they don't want to use poison, the only remaining option is to hand pick them and dispatch as necessary. Look upon it as you would weeding.
