Beetle
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 har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandracottus Rotundus
Chandragupta Maurya (350-295 BCE) was a ruler in Ancient India who expanded a geographically-extensive kingdom based in Magadha and founded the Maurya dynasty. He reigned from 320 BCE to 298 BCE. The Maurya kingdom expanded to become an empire that reached its peak under the reign of his grandson, Asoka, from 268 BCE to 231 BCE. The nature of the political formation that existed in Chandragupta's time is not certain. The Mauryan empire was a loose-knit empire. Quote: "The geography of the Mauryan Empire resembled a spider with a small dense body and long spindly legs. The highest echelons of imperial society lived in the inner circle composed of the ruler, his immediate family, other relatives, and close allies, who formed a dynastic core. Outside the core, empire travelled stringy routes dotted with armed cities. Outside the palace, in the capital cities, the highest ranks in the imperial elite were held by military commanders whose active loyalty and success in war deter ...

Dytiscidae
The Dytiscidae – based on the Greek ''dytikos'' (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between long, though much variation is seen between species. The European '' Dytiscus latissimus'' and Brazilian '' Megadytes ducalis'' are the largest, reaching up to and respectively. In contrast, the smallest is likely the Australian '' Limbodessus atypicali'' of subterranean waters, which only is about long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
