Liloceris lilii

The red or scarlet lily beetle (Lilioceris lilii) is a leaf beetle that eats the stems, leaves, buds and flowers of lilies, fritillaries and other plants in the Liliaceae family. It only lays its eggs on Liliuim and Fritillaria species [1]. It is native to parts of Eurasia. It is known to have been introduced separately to Britain and Canada in the 1940s, possibly on imported lily bulbs. It is now a pest in most temperate climates where lilies are cultivated.
The larvae have orange-brown bodies and black heads. They carry their excrement on their backs in order to deter predators. Adults are bright scarlet in colour and 6–9 mm long.
When the adult beetles are threatened they emit a high pitched buzzing from their abdomen.
