Guillaume-Antoine Olivier
Guillaume-Antoine Olivier (; 19 January 1756, Les Arcs near Toulon – 1 October 1814, Lyon) was a French entomologist and naturalist. Life Olivier studied medicine in Montpellier, where he became good friends with Pierre Marie Auguste Broussonet. With Jean Guillaume Bruguière and Jean-Baptiste Lamarck, he collaborated in the creation of ''Journal d'Histoire Naturelle'' (1792). Afterwards, he served as a naturalist on a 6-year scientific journey that took him to Asia Minor, Persia, Egypt, Cyprus and Corfu. He returned to France in 1798 with a large collection of natural history specimens from his travels. Later, he was associated with the ''École nationale vétérinaire d'Alfort'', where in 1811, he was appointed professor of zoology. Olivier was a close friend of Johan Christian Fabricius and a patron of Pierre André Latreille. Although primarily an entomologist, Olivier also worked in the scientific field of herpetology, describing several new species of Asian lizards. ...

François-Louis Laporte, Comte De Castelnau
François-Louis Nompar de Caumont Laporte, comte de Castelnau (born ''François-Louis Nompar de Caumont La Force''; 24 December 1802 – 4 February 1880) was a French naturalist, known also as François Laporte or Francis de Castelnau. The standard author abbreviation Castelnau is used to indicate him when citing a botanical name and zoological names other than insects. Laporte is typically used when citing an insect name, or Laporte de Castelnau. Life Born in London, Castelnau studied natural history in Paris. From 1837 to 1841 he traveled in the United States, Texas, and Canada. He visited Middle Florida from November 1837 until March 1838, publishing "Essai sur la Floride du Milieu" in 1843. In Canada he studied the fauna of the Canadian lakes and the river systems of Upper and Lower Canada (roughly corresponding to the modern provinces of Ontario and Quebec) and of the United States. Castelnau, a French savant, was sent by Louis Philippe, in 1843, with two botanists and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarabaeus
The genus ''Scarabaeus'' consists of a number of Old World dung beetle species, including the "sacred scarab beetle", ''Scarabaeus sacer'' and typical of the tribe Scarabaeini. These beetles feed exclusively on dung, which they accomplish by rolling a piece of dung some distance from where it was deposited, and burying it in order to feed on it underground. They also prepare food for their larvae by excavating an underground chamber, and filling it with balls that have eggs laid in them. The growing larva feeds upon the dung ball, pupates, and eventually emerges as an adult. A "scarabaeus" is also a now outdated term (OED 2) for an object in the form of a scarab beetle in art. The scarab was a popular form of amulet in Ancient Egypt, and in ancient Greek art engraved gems were often carved as scarabs on the rest of the stone behind the main flattish face, which was used for sealing documents. A creature identified as Scarabaeus appears in "The Gold-Bug" by Edgar Allan P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarabaeidae
The family Scarabaeidae, as currently defined, consists of over 30,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Bouchard (2011). Description Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between . They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into a ball or fanned out like leaves to sense odours. Many species are fossorial, with legs adapted for digging. In some groups males (and sometimes females) have prominent horns on the head and/or pronotum to fight over mates or resources. The largest fossil scaraba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deltochilini
Deltochilini (or Canthonini) is a tribe of scarab beetles, in the dung beetle subfamily (Scarabaeinae). Members of this group vary widely in size (2–33 mm long) and shape, but were thought to be derived from an ancient ball-rolling lineage. The outer edges of the front tibiae have less than four teeth. The grouping based on these characteristics has, however, been found to have little phylogenetic validity, and the placement of several genera in the tribe is likely to change. Taxonomy There has been some controversy regarding the valid name for this tribe. Deltochilini is the senior name, and has precedence under the ICZN, but in 2006, Smith suggested that the name Canthonini, though junior, might be preserved under Code Article 35.5, which can be used to preserve junior names if they are higher in taxonomic rank than the senior names of constituent taxa.Smith, A.B.T.

Beetles Described In 1789
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 exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Of Brazil
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] |
Arthropods Of Colombia
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-lik ...
