Ludwig Redtenbacher
Ludwig Redtenbacher (June 10, 1814 in Kirchdorf an der Krems, Austria – February 8, 1876 in Vienna) was an Austrian doctor and entomologist mainly interested in beetles. He was the brother of the chemist Josef Redtenbacher (1810–1870). From 1833 to 1838, he studied medicine at the University of Vienna, becoming a salaried trainee in 1840. In 1843, he earned his medical doctorate, afterwards working as an assistant with the entomological collection of the ''Hofnaturalienkabinett'' (from 1847). In 1851, he became a professor of zoology in Prague and, from 1860, he was director of the Vienna Natural History Museum. Although Redtenbacher worked mainly on the beetles of Austria, his new approach to classification or, in German, "''analytischen''" was widely adopted. He is also significant for his work involving beetles collected on the voyage of the ''Novara'', an Austrian frigate that went on a round-the-world scientific expedition between 1857 and 1859. He also described many of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mordellidae
The Mordellidae are a family of beetles commonly known as tumbling flower beetles for the typical irregular movements they make when escaping predators, or as pintail beetles due to their abdominal tip which aids them in performing these tumbling movements. Worldwide, there are about 1500 species. Anatomy The apparently tumbling movements are composed of a series of very rapid separate jumps (each jump of a duration of approximately 80 ms). They result from the beetle's efforts to get itself back into take-off position for flight when it has been in either lateral or dorsal position. Each individual jump should be considered as an extended rotation, performed by one leg of the third leg pair (metapodium). Depending on whether the left or the right metapodium is used as the leg that provides the leverage for take-off, change occurs in the direction of the jump. The energy for propulsion varies with the beetle's immediate muscle work, so that jump lengths and heights vary, with ro ...
