Chalcosoma Atlas
The Atlas beetle (''Chalcosoma atlas'') is a very large species of beetle in the family Scarabaeidae, found in Southeast Asia. Males have three prominent horns. The species is named for Atlas, the giant of Greek mythology who supported the skies. Description ''Chalcosoma atlas'', like other beetles of the genus '' Chalcosoma'', is remarkable for its size. As is common in the Scarabaeidae, males are larger than the females, reaching a length of about ; females are about . Males have specialised horns on their head and thorax that they use to fight with each other, to gain mating rights with females. The Atlas beetle differs from other ''Chalcosoma'' species (such as '' C. caucasus'') by the broader end of the cephalic (head) horn. Larvae The larva of the Atlas beetle is known for its fierce behavior, including biting if touched. Unverified reports exist of larvae that live together fighting to the death if they have insufficient space or food. Distribution ''Chalcosoma atlas'' i ...

Chalcosoma Moellenkampi
The Moellenkampi beetle (''Chalcosoma moellenkampi''), is one of four large species of rhinoceros beetles from Southeast Asia belonging to the genus ''Chalcosoma''. The Moellenkampi beetles belong to the beetle family Scarabaeidae along with other rhinoceros beetles. They are characterized by having two large, forward-projecting horns on the pronotum or thorax, and another large, forward and upward-projecting horn on the head. They also have a distinct metallic lustre, which is the reason behind their genus name, which derives from Greek, ', and is the combining form of ', meaning copper. Distribution Unlike its close relatives, ''C. atlas'', ''C. chiron'', and ''C. engganensis'', ''C. moellenkampi'' has a rather restricted geographic distribution and appears to occur only on Borneo. Description ''Chalcosoma moellenkampi'' can reach about the same size as ''C. atlas'', and males may measure up to from the tip of the head horn to the end of the elytra (wingcases).

Chalcosoma Chiron
''Chalcosoma chiron'' (often called the Caucasus beetle) is a species of beetle in the family Scarabaeidae. This species can be found from Malaysia south into Indonesia (Sumatra, Java, Malay Peninsula, Indochina) and Thailand in East region ( Chanthaburi province, Sa Kaeo province). It was formerly known as ''Chalcosoma caucasus'', a name which is a junior synonym and not valid. Description ''Chalcosoma chiron'' males can reach a length of , while females grow to . Caucasus beetles are the largest of the genus ''Chalcosoma'' and one of Asia's largest beetles. They have a striking sexual dimorphism. The male has specialised enormous, curved horns on its head and thorax that it can use to fight with other males to gain mating rights with females. A female is significantly smaller. The elytra of the females have a velvety texture, as they are covered by tiny hairs. When males enter into contests for females, the fighting spirit is as strong as in the Hercules beetle of South Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chalcosoma Janssensi
''Chalcosoma chiron'' (often called the Caucasus beetle) is a species of beetle in the family Scarabaeidae.

Rhinoceros Beetles
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1500 species and 225 genera of rhinoceros beetles are known. Many rhinoceros beetles are well known for their unique shapes and large sizes. Some famous species are, for example, the Atlas beetle (''Chalcosoma atlas''), common rhinoceros beetle (''Xylotrupes ulysses''), elephant beetle (''Megasoma elephas''), European rhinoceros beetle (''Oryctes nasicornis''), Hercules beetle (''Dynastes hercules''), Japanese rhinoceros beetle or ''kabutomushi'' (''Allomyrina dichotoma''), ox beetle (''Strategus aloeus'') and the Eastern Hercules beetle (''Dynastes tityus''). Description and ecology The Dynastinae are among the largest of beetles, reaching more than in length, but are completely harmless to humans because they cannot bite or st ...

Chalcosoma Engganensis
''Chalcosoma engganensis'' is a large (35–60 mm) and heavy beetle. The body is shiny black. The male has a sharp horn (directed obliquely upward and forward) on the head. On each side of pronotum there are curved, forward directed horns. Across the head there is a short but powerful spike. This species differs from the normally developed specimens of the other ''Chalcosoma'' species in that horns are shorter, male can look a lot like small copies of ''Chalcosoma moellenkampi The Moellenkampi beetle (''Chalcosoma moellenkampi''), is one of four large species of rhinoceros beetles from Southeast Asia belonging to the genus ''Chalcosoma''. The Moellenkampi beetles belong to the beetle family Scarabaeidae along with oth ...''. The female lacks these horns and spikes, and is smaller.

List Of Largest Insects
Insects, which are a type of arthropod, are the most numerous group of multicellular organisms on the planet, with over a million species identified so far. The title of heaviest insect in the world has many contenders, the most frequently crowned of which is the larval stage of the goliath beetle, '' Goliathus goliatus'', the maximum size of which is at least and . The highest confirmed weight of an adult insect is for a giant weta, ''Deinacrida heteracantha'', although it is likely one of the elephant beetles, '' Megasoma elephas'' and ''Megasoma actaeon'', or goliath beetles, both of which can commonly exceed and , can reach a greater weight. The longest insects are the stick insects, see below. Representatives of the extinct dragonfly-like order Meganisoptera (also known as griffinflies) such as the Carboniferous ''Meganeura monyi'' and the Permian ''Meganeuropsis permiana'' are the largest insect species ever known. These creatures had a wingspan of some . Their maxim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
