Since beetles form such a large part of the world's biodiversity, their conservation is important, and equally, loss of habitat and biodiversity is essentially certain to impact on beetles. Many species of beetles have very specific habitats and long life cycles that make them vulnerable.
The hercules beetle, the world's longest beetle. Beetles constitute the most diverse order of organisms on earth, with about 400,000 species identified to this day. The most massive of them belong to the genera Goliathus, Megasoma, Chalcosoma, Titanus, Macrodontia, and Xixuthrus.
Articles relating to the Beetles (order Coleoptera), insects 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 insects and 25% of all ...
Recent figures indicate that there are more than 1.4 billion insects for each human on the planet, [27] or roughly 10 19 (10 quintillion) individual living insects on the earth at any given time. [28] An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. [28]
Some dytiscid species are also found in brackish water. [5] Diving beetles live in water bodies in various landscapes, including agricultural and urban landscapes. [6] [7] [8] Some species, such as Agabus uliginosus [6] and Acilius canaliculatus, [8] are found to be relatively tolerant to recent urbanization. One of the most important limiting ...
From the world's largest beetle, the Hercules beetle which measures up to 16.7 cm, to the smallest, a featherwing beetle Scydosella musawasensis which may measure as little as 0.325 mm in length, to the colourful Chrysolina cerealis, the familiar Coccinellidae, and the nuisance Colorado potato beetle, there is huge variation in the world of ...
Others, such as the Japanese beetle, are plant-eaters, wreaking havoc on various crops and vegetation. Some of the well-known beetles from the Scarabaeidae are Japanese beetles, dung beetles, June beetles, rose chafers (Australian, European, and North American), rhinoceros beetles, Hercules beetles and Goliath beetles.
For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered insects are listed ...
