Félix Édouard Guérin-Méneville
Félix Édouard Guérin-Méneville, also known as F. E. Guerin, (12 October 1799, in Toulon – 26 January 1874, in Paris) was a French entomologist. Life and work Guérin-Méneville changed his surname from Guérin in 1836. He was the author of the illustrated work ''Iconographie du Règne Animal de G. Cuvier 1829–1844'', a complement to the work of the zoologists Georges Cuvier and Pierre André Latreille, ''Le Règne Animal'', which illustrated only a selection of the animals covered. Cuvier was delighted with the work, saying that it would be very useful to readers, and that the illustrations were "as accurate as they were elegant". He also introduced silkworms to France, so they could be bred for the production of silk. Guérin-Méneville founded several journals: ''Magasin de zoologie, d’anatomie comparée et de paléontologie'' (1830), ''Revue zoologique par la Société cuviérienne'' (1838), ''Revue et Magasin de zoologie pure et appliquée'' (1849), and ''Revue de ...

Chrysomelidae
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up 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 the 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. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, ...

Stereospermum Tetragonum
''Stereospermum tetragonum'', the yellow snake tree, is 15–20 m tall, trunk 15–25 cm in diam, large leaves 25–50 cm; leaflets 3–6 on each side of midrib, long elliptic, 8-14 X 2.5–6 cm. Large, pale yellow, trumpet shaped flowers occur in panicles. Flowers are pale yellow, slightly curved, about 2 cm, upper lip 2-lobed, lower lip 3-lobed, tomentose at mouth, tube terete. The fruit is long, 4-angular, slightly curved, 30–70 cm, about 1 cm in diameter. This, probably, is the source of its common name, snake tree. Also known as ''Stereospermum colais'', it is found in India, Myanmar and Sri Lanka: where it is "common in moist deciduous forests and occasional in openings or margins of evergreen forests, up to 1200 m." In Vietnam, Stereospermum colais is known as . Its young leaves can be eaten as a vegetable in Vietnam's Central Highlands. References tetragonum {{Tree-stub ...

Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change the colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are leaf miners, while the cassidoids feed on the plant surfaces, sometimes covering their bodies with faecal shi ...

Insects Of Sri Lanka
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Described In 1798
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
