Plaesius Javanus
''Plaesius javanus'', the Jepson's beetle, is a species of clown beetles belonging to the family Histeridae. Description ''Plaesius javanus'' can reach a length of about . These beetles have a glossy black body, with long and curved jaws and short antennae. Frontlegs are thin and expanded laterally. Elytra show 4–6 longitudinal grooves. Two abdominal rear segments are exposed. These predatory histerid beetles have been introduced in some countries for the control of the banana weevil borer (''Cosmopolites sordidus ''Cosmopolites sordidus'', commonly known as the banana root borer, banana borer, or banana weevil, is a species of weevil in the family Curculionidae. It is a pest of banana cultivation and has a cosmopolitan distribution, being found in all pa ...''). Distribution This species is native to Southeastern Asia and Indonesia.

Wilhelm Ferdinand Erichson
Dr Wilhelm Ferdinand Erichson (26 November 1809 in Stralsund – 18 December 1848 in Berlin) was a trained medical doctor and a German entomologist. He was the author of many articles about insects mainly in ''Archiv für Naturgeschichte''. When writing in Latin, he latinised ''Wilhelm'' to ''Guillelmus'' becoming either ''Guil. F. Erichson'' or ''G.F. Erichson.'' He wrote a paper in 1842 on insect species collected at Woolnorth in Tasmania, Australia, which was the first detailed research published on the biogeography of Australian animals and was very influential in raising scientific interest in Australian fauna. Erichson was the curator of the Coleoptera collections at the ''Museum fur Naturkunde'' in Berlin from 1834 to 1848. Erichson's Scarabaeidae classification is nearly identical to the modern one.

Histeridae
Histeridae is a family of beetles commonly known as clown beetles or Hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other Hister beetles, they must be isolated when collected. Characteristics The Hister beetles are easily identified by their shiny elytra which is typically shiny black or metallic green. The two main shapes for this family are oval a ...

Cosmopolites Sordidus
''Cosmopolites sordidus'', commonly known as the banana root borer, banana borer, or banana weevil, is a species of weevil in the family Curculionidae. It is a pest of banana cultivation and has a cosmopolitan distribution, being found in all parts of the world in which bananas are grown. It is considered the most serious insect pest of bananas. Description The adult banana root borer is about in length and has a glossy greyish-black or dark brown appearance. Unlike the billbugs (''Sphenophorus''), the thorax lacks depressions. The tibia of each of the limbs bears an accessory hook-like claw with which the insect clings to plants. The larva is plump and whitish with a reddish-brown head. The eighth abdominal segment of the larva bears a large spiracle, the remaining segments bearing small spiracles; the last two segments appear truncated, being fused together to form a plate-like structure. The pupa has an irregular appearance, with the developing wings and limbs being discerna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Of Asia
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 exos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
