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.
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, [1] including more than 500 genera and 7000 species. [2] They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red.
There is a similar-looking pest species of leaf beetle in a related genus, Plesispa reichei, also sometimes referred to as the "coconut leaf beetle", which is distinguished only with some difficulty from B. longissima; primarily by its slightly broader body and stronger punctation.
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, a paraphyletic group which Apocrita (wasps, bees and ants) evolved from), and flies . Some beetles also exhibit this behavior.
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.
Their results show the general relationship between the genera, but when comparing female and male representatives, they do not yet provide a clear phylogenetic picture of the recent genera. [ 11 ] Cladograms of the Phylliidae species determined on the basis of molecular genetics analysis and morphological investigations according to Cumming ...
Some ladybird beetles, including Calvia quindecimguttata and Oenopia conglobata consume leaf beetle larvae, while other aphid specializing ladybirds do not consume them. [ 39 ] [ 49 ] [ 50 ] The larval secretion of P. vitellinae contains salicylaldehyde, an irritating volatile compound that was shown to repel ants in the laboratory. [ 9 ]
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.
