Megaderus Stigma
''Megaderus stigma'' is a species of long-horned beetle in the family Cerambycidae. It is found in Nicaragua, Costa Rica, Panama, Trinidad & Tobago, Colombia, Venezuela, Guyana, Suriname, French Guiana, Brazil (Paraíba, Pernambuco, Alagoas, Bahia, Mato Grosso, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul), Peru, Bolivia, Paraguay, Argentina and Uruguay. This species was described by Linnaeus. He described it as: ''Cerambyx'' sub-short, roundish, coarsely punctate, body dark, elytra An elytron (; ; : elytra, ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometime ... smooth: with white macula. Habitat in America. Rolander. Totally black. thorax hemispherical, sub-margined, abundantly coarsely punctate, posteriorly excavated close to lateral tooth. Scutellum smo ...

Long-horned Beetle
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. Most species are characterized by antennae as long as or longer than the beetle's body. A few species have short antennae (e.g., '' Neandra brunnea''), making them difficult to distinguish from related families such as Chrysomelidae. "Cerambycidae" comes from a Greek mythological figure: after an argument with nymphs, the shepherd Cerambus is transformed into a large beetle with horns. Longhorn beetles are found on all continents except Antarctica. Description Other than the typical long antennal length, the most consistently distinctive feature of adults of this family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elytra
An elytron (; ; : elytra, ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripipho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beetles Described In 1758
Beetles are insects that form the 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 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 ladybugs) eat a ...
