The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) [citation needed] species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families.
Chrysochus auratus, more commonly known as the dogbane beetle, is a leaf beetle primarily found in the eastern United States. The beetle is approximately 8 to 11 mm in length, and possesses an oblong and convex shape. This beetle has two pairs of wings, one of which is a pair of copper colored elytra.
The wing cases of the lily leaf beetle are dimpled and are shinier and more rounded than those of the cardinal beetle, which are relatively dull, and narrower, flatter, and more elongated. The cardinal beetle also has comb-like antennae. [5] The lily leaf beetle is herbivorous, while the cardinal beetle preys on insects. [6]
Galerucella calmariensis, sometimes Neogalerucella calmariensis, is a species of leaf beetle in the family Chrysomelidae. It is commonly known as the black-margined loosestrife beetle and is native to Europe and Northern Asia (excluding China) where both adults and larvae feed on purple loosestrife (Lythrum salicaria).
To determine the eating habits of O. melanopus, scientists conducted an experiment using different media. They took agar gel infused with pea and barley extracts, and noted the resulting reaction. When used alone, both pea extract, which is not a desired food for the beetle, and barley extract, which is an alternate source, produced a weakening ...
These beetles should not be confused with the 'green mint beetle' (or Chrysolina herbacea), as it is greener in appearance (emerald green, [4]) and slightly larger in size, [2] as C. herbacea measures 7–11 mm in length. [7] C. herbacea and Chrysolina graminis (tansy beetle) both have a mixture of fine and coarse punctures on the pronotal disk ...
Chrysolina cerealis can reach a length of 5.5–10 millimetres (0.22–0.39 in). [5] Females are typically larger than males. [5] Coloration of the pronotum and the elytra is quite variable, usually it is metallic green with three blue and red longitudinal stripes, with golden reflections (hence the common name).
The Chrysomelinae are a subfamily of leaf beetles (Chrysomelidae), commonly known as broad-bodied leaf beetles or broad-shouldered leaf beetles. It includes some 3,000 species around the world. [1] The best-known member is the notorious Colorado potato beetle (Leptinotarsa decemlineata), an important agricultural pest.
