Scarlet beetles (6mm - 8mm long) with black heads eat the leaves, flowers and seedpods of lilies and other members of the lily family. Don't mistake them for ladybirds. Between April and September the beetles lay eggs on the undersides of leaves. After a week they hatch into reddish-brown maggot-like grubs, and feed on the same parts of the plant as the parents. Possibly to deter predators or disguise themselves, the larvae cover themselves in their own wet, black excrement.
Lily leaves are shredded and may be covered in brown-black droppings.
