Chrysolina
''Chrysolina'' is a large genus of leaf beetles in the subfamily Chrysomelinae. Most species are distributed in Europe, Asia and Africa with a small number of species inhabiting North America (including introduced European ones) and introduced species in Australia. The species '' Chrysolina cerealis'' and '' C. graminis'' are protected in the United Kingdom. All species of ''Chrysolina'' are phytophagous, feeding on specific food plants, and some of them have been used for biological control of weeds. To control ''Hypericum perforatum'' (St John's wort), '' C. hyperici'' was successfully naturalized in Australia in the 1930sWilfred William Robbins, Alden Springer Crafts.

Chrysolina Hyperici
''Chrysolina hyperici'', the Saint John's wort beetle is a species of beetles of the family Chrysomelidae. Life cycle The species lays up to 2,000 eggs on the host plant during the early fall. They lay their eggs on the undersides of leaves of new fall basal growth on its host plant, St. John's Wort (''Hypericum perforatum''). The larvae feed for a month on the leaves, emerging at night and hiding during the day. When full grown they move to the soil to pupate. After two weeks they emerge as adults. In the spring the adults feed upon new growth of their host plant. Taxonomy The species is most often classified as ''Chrysolina hyperici'' (Forster, 1771), however it was originally placed in the genus '' Chrysomela'' as ''Chrysomela hyperici''. It was first scientifically described and named by Johann Reinhold Forster in ''Novæ species insectorum'' in the year 1771. Within the genus '' Chrysolina'', the species is classified in the subgenus '' Hypericia''. It is closely related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysolina Bicolor (Fabricius, 1775) (2991758086)
''Chrysolina bicolor'' is a species of beetle belonging to the Chrysomelidae family. Description ''Chrysolina bicolor'' reaches about in length, with females slightly larger than males. Pronotum is usually metallic blue. Elytra are densely punctured and vary from metallic green to reddish, sometimes with darker violet spots. The main host plants are lavender, oregano Oregano (, ; ''Origanum vulgare'') is a species of flowering plant in the mint family, Lamiaceae.

Chrysolina Quadrigemina
''Chrysolina quadrigemina'' is a species of beetle of the family Chrysomelidae. The species was described by Christian Wilhelm Ludwig Eduard Suffrian in 1851. It is native to Europe and North Africa. It feeds on ''Hypericum perforatum'' and other members of the genus. This plant is an introduced invasive pest in North America and Australia. The beetle was introduced in these regions as a biological control. Description ''Chrysolina quadrigemina'' completes one lifecycle each year. They start with egg laying in the fall laying their eggs on the undersides of leaves of new fall basal growth on its host plant, St. John's Wort (''Hypericum perforatum''). The larvae feed on the plants at night for around one month before burying themselves in the soil to pupate. In this time they will often completely destroy the fall growth of their host plant. The insects remain in individual pupation chambers over the winter. In late spring the adults emerge to feed heavily on the plants just be ...

Hypericum Perforatum
''Hypericum perforatum'', commonly known as St. John's wort (sometimes perforate St. John's wort or common St. John's wort), is a flowering plant in the family Hypericaceae. It is a hairless, Perennial, perennial herb with woody Root, roots, yellow Flower, flowers marked by black glands, and leaves that appear Perforation, perforated due to translucent glands, producing thousands of seeds per plant. ''H. perforatum'' is the type species of its genus, known for its historical use in folklore and traditional medicine. Probably a Hybrid (biology), hybrid between the closely related ''Hypericum attenuatum, H. attenuatum'' and ''Hypericum maculatum, H. maculatum'' (imperforate St. John's wort) that originated in Siberia, the species has Cosmopolitan distribution, spread worldwide. It can further hybridize with related species due to its Polyploidy, allopolyploid nature. It is native to much of Europe, West Asia, West and Central Asia, and parts of Africa and China and has been wide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leaf Beetle
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...
