Beetles
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 ...

Elateridae
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. The evolutionary purpose of this click is debated: hypotheses include that the clicking noise deters predators or is used for communication, or that the click may allow the beetle to "pop" out of the subtrate in which it is pupating. It is unlikely that the cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adrastus Rachifer
In Greek mythology, Adrastus or Adrestus (Ancient Greek: Ἄδραστος or Ἄδρηστος), (perhaps meaning "the inescapable"), was a king of Argos, and leader of the Seven against Thebes. He was the son of the Argive king Talaus, but was forced out of Argos by his dynastic rival Amphiaraus. He fled to Sicyon, where he became king. Later he reconciled with Amphiaraus and returned to Argos as its king. Because of an oracle Adrastus married his daughters to the exiles Polynices and Tydeus and promised to restore them to their homelands. He first assembled an army to place Polynices on the throne of Thebes, led by seven champions, famously called the Seven against Thebes. The expedition failed and all the champions died except Adrastus, saved by his divine horse Arion. He went with the Epigoni, the sons of the Seven, in the successful second war against Thebes, and was said to have died on his way home. Adrastus is mentioned as early as Homer's ''Iliad'', and his story was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
