Goliathus albosignatus |
The Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Beetles are the group of Insects with the largest number of known Species. The family Scarabaeidae as presently defined consists of over 30000 species of Beetles worldwide Flower chafers are a group of scarab beetles, subfamily Cetoniinae Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for The largest organism found on earth can be measured using a variety of methods They are members of subfamily Cetoniinae, within the scarab beetle family. Flower chafers are a group of scarab beetles, subfamily Cetoniinae Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. Goliath beetles measure from 60–110 mm for males and 50-80 for females, as adults, and can reach weights of up to 80-100 grams (3 to 3-1/2 oz) in the larval stage, though the adults are only about half this weight. A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example The heavily armored adults are so large that when flying, they produce a sound akin to a toy helicopter in flight. History Since 400 AD Chinese children have played with bamboo flying toys. The females range from a dark brown to silky white, but the males are nomally brown/white/black or black/white.

Classification
Goliath beetles are members of the insect order Coleoptera, family Scarabaeidae, subfamily Cetoniinae, tribe Goliathini, genus Goliathus. Beetles are the group of Insects with the largest number of known Species. The family Scarabaeidae as presently defined consists of over 30000 species of Beetles worldwide Flower chafers are a group of scarab beetles, subfamily Cetoniinae
Habitat
All Goliathus species are native to Africa. They are primarily tropical, although one species, G. albosignatus, is localized in the more temperate southeastern portion of Africa. It is in the continent's equatorial rain forests that the Goliath beetles have reached their greatest diversity.
Life cycle
The female Goliathus lays its eggs in soil early in the rainy season. Goliathus larvae are somewhat unusual among cetoniine scarabs in that they have a greater need for high protein foods than do those of most other genera. Proteins are large Organic compounds made of Amino acids arranged in a linear chain and joined together by Peptide bonds between the Carboxyl Pellets of dry or soft dog or cat food (buried in the rearing substrate on a regular schedule) provide a suitable diet for Goliathus larvae in captivity. However, a substrate of somewhat moistened, decayed leaves and wood should still be provided in order to create a suitable medium for larval growth. The young stage larvae (1st instar) will eat some of this material. Even under optimum conditions, the larvae take a number of months to mature fully because of the great size they attain. They are capable of growing up to 150 mm in length, and reaching weights in excess of 100 grams. For other uses of the words gram or gramme see Gram (disambiguation. When maximum size is reached, the larva constructs a rather thin walled, hardened cell of sandy soil in which it will undergo metamorphosis (pupation) to the adult state. A pupa ( Latin pupa for doll pl pupae or pupas) is the life stage of some Insects undergoing transformation Once building of this cocoon is completed, the larva transforms to the pupal stage, which is an intermediate phase between the larval and adult stages. A pupa ( Latin pupa for doll pl pupae or pupas) is the life stage of some Insects undergoing transformation During the pupal duration, the insect's tissues are broken down and re-organized into the form of the adult beetle. Once metamorphosis is complete, the insect sheds its pupal skin and undergoes a period of hibernation as an adult beetle until the dry season ends. When the rains begin, the beetle breaks open its cocoon, locates a mate, and the entire life cycle starts over again. The adult beetles feed on materials rich in sugar, especially tree sap and fruit. Sugar is a class of edible Crystalline substances mainly Sucrose, Lactose, and Fructose. Under captive conditions, adults can sometimes live for about a year after emerging from their pupal cells. Longevity in the wild is likely shorter on average due to factors such as predators and weather. The adult phase concentrates solely on reproduction (sex), and once this function is performed, the time of the adult beetle is limited, as is true for the vast majority of other insect species.
