Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. 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. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). 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 ...

Bostrichoidea
Bostrichoidea is a Taxonomic rank, superfamily of beetles. It is the type superfamily of the infraorder Bostrichiformia. Description The Bostrichoidea are united by the following features: modified cryptonephridism, the structure of the aedeagus in males, and the lack of a basal mandibular mola in larvae. Aside from this, Bostrichoidea show a range of morphologies. For example, in Bostrichidae alone, the adult body shape varies from convex to flattened, the body length from , and the colour may be yellow, brown or black and sometimes has a metallic hue. Ecology Bostrichoids generally live in dry habitats. For example, many Bostrichidae Xylophagy, feed on wood, though some attack Monocotyledon, monocotyledonous plants as well and Rhyzopertha, ''Rhyzopertha dominica'' feeds on stored grains and cereal products. Similarly, most Ptinidae are wood-borers as larvae but some feed on other dry plant or animal material, such as stored foods, tobacco and museum specimens. Dermestidae ...

Bostrichidae
The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles, or horned powderpost beetles. Anatomy The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. Exceptions are the powderpost beetles (subfamily Lyctinae), and members of the subfamily Psoinae. ''Bostrychoplites cornutus'' has large, distinctive thoracic horns, and is found in parts of Africa and Arabia; it is often imported to Europe as larvae in African wooden bowls ("ethnic souvenirs") . Fossils The fossil record of the family extends to the Cretaceous, with the oldest records being from the Cenomanian aged Charentese and Burmese ambers, belonging to the extant genus '' Stephanopachys'' and the extant subfamilies Dinoderinae and Polycaoninae. Selected species This list is incomplete: * '' Amphicerus cornutus'' (Pallas, 1772) * '' Apate terebrans'' (Pallas, 1772) * '' ...

Lyctinae
Powderpost beetles are a group of seventy species of woodboring beetles classified in the insect subfamily Lyctinae. These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax, powderpost beetles do not, making their heads more visible. In addition to this, their antennae have two-jointed clubs. They are considered pests and attack deciduous trees, over time reducing the wood to a powdery dust. The damage caused by longhorn beetles (family Cerambycidae) is often confused with that of powderpost beetles, but the two groups are unrelated. The larvae of the Cerambycidae are white, straight and generally flat-headed, whereas those of the Bostrichidae are white and C-shaped. Name The term "powderpost" comes from the fact that the larvae of these beetles feed on wood and, given enough time, can reduce it to a mass of fine powder. Because of th ...

Francis Polkinghorne Pascoe
Francis Polkinghorne Pascoe (1 September 1813 – 20 June 1893) was an English entomologist mainly interested in beetles. Biography He was born in Penzance, Cornwall and trained at St. Bartholomew's Hospital, London. Appointed surgeon in the Navy he served on Australian, West Indian and Mediterranean stations. He married a Miss Mary Glasson of Cornwall and settled at Trewhiddle near St Austell where his wife's property produced china clay. Widowed in 1851 he settled in London devoting himself to natural history and entomology in particular. The results of collecting trips to Europe, North Africa and the Lower Amazons were poor and Pascoe worked mainly on insects collected by others. His entomological papers listed and described species collected by Alfred Russel Wallace (in ''Longicornia Malayana''), Robert Templeton and other assiduous collectors but not prolific writers on systematic entomology. He became a Fellow of the Entomological Society in 1854, was president from 1864 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Woodboring Beetle
The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers. Woodboring is thought to be the ancestral ecology of beetles, and bores made by beetles in fossil wood extend back to the earliest fossil record of beetles in the Early Permian (Asselian), around 295-300 million years ago. Ecology Woodboring beetles usually attack dying or dead trees. In forest settings, they are important in the turnover of trees by culling weak trees, thus allowing new growth to occur. They are also important as primary decomposers of trees within forest systems, allowing for the recycling of nutrients locked away in the relatively decay-resilient woody material of trees.
