The beautiful scarlet lily beetle (Lilioceris lilii) is a parasitic insect to a lot of plants of the Liliaceae family, mainly on fritillaries. It feeds on the leaves and flowers of the plant and also lays its eggs (up to 450) under the leaves. It is a species of the Palaearctic that, in the recent years, has been invading North America, where its presence has caused great damage to gardens that cultivate plants of the Liliaceae family. In our country you can see it almost in every fritillary. A beautiful sight and subject for photography as the bright red color emerges even more with the dark-colored petals. Here, a scarlet lily beetle upon the impressive, endemic black fritillary of Attica (Fritillaria obliqua subsp obliqua).
