Scarlet Lily Beetle

A type of leaf beetle known as the Scarlet Lily Beetle feeds on the leaves, stems, buds, and flowers of lilies, fritillaries, and other Liliaceae plants. It is also referred to as the Red Lily Beetle or Lily Leaf Beetle. It prefers to lay its eggs on Fritillaria and Lilium plants. In the absence of Lilium and Fritillaria species, fewer eggs are laid, and the survival rate of eggs and larvae is decreased. It is currently regarded as a pest in the majority of temperate climates where lilies are produced.

The adult lily beetle has rather long legs and antennae and is between 6 and 9 mm in length. It has vivid scarlet and lustrous elytra (harder forewings). Its head, legs, eyes, antennae, and underside are all covered with black. It features a broad abdomen, huge eyes, and a narrow thorax. There are 11 segments on each antenna. There are two grooves on the thorax and the eyes are notched.
