Scarlet lily beetle

The scarlet lily beetle (Lilioceris lilii), or red / leaf lily beetle, is a leaf beetle that eats the leaves, stem, buds and flower of lilies, fritillaries and other members of the family Liliaceae. They mainly lay their eggs on Lilium and Fritillaria species. Observed in absence of Lilium andFritillaria species, the numbers of eggs laid were significantly less and the survival rate of eggs and larvae were lowered. It is now a pest in most temperate climates where lilies are cultivated. Lily leaf beetles overwinter in the soil and come out early in spring whereas adults stay in moist environments .





It has also become an invasive alien insect in the United Kingdom, where it has established itself after its introduction in 1943. It has since spread from Surrey to as far north as Glasgow
