Agabetes Acuductus
''Agabetes acuductus'' is a species of predaceous diving beetle found in the United States and Canada. Its habitat includes wooded wetlands, in the leaf litter of shaded pools, and cattail ''Typha'' is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae.

Dytiscidae
The Dytiscidae, from the Ancient Greek word δυτικός (''dystikos''), meaning "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 in terrestrial habitats such as among leaf litter. The “diving” in their common name comes from their cycling between underwater and the surface to replenish oxygen like a diver. The adults of most are between long, though much variation is seen between species. The European '' Dytiscus latissimus'' and Brazilian '' Bifurcitus ducalis'' are the largest, reaching up to respectively, although the latter is listed as extinct by the IUCN. 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 appe ...

George Robert Crotch
George Robert Crotch (1842 – 16 June 1874) was a British entomologist and an authority on Coleoptera (beetles), particularly the Coccinellidae, ladybird beetles. He was the grandson of the English composer and organist William Crotch. Biography Born in Taunton, Somerset, England, the son of Reverend W. R. Crotch, he became interested in insects in his childhood. He collected in the Fens and wrote notes from the age of fourteen. He matriculated from St John's College, Cambridge, St. John's College, Cambridge in 1861 and graduated in 1864. He became more keen on the Coleoptera. He worked as a second assistant librarian in 1866 at the University Library, Cambridge and worked on an MA. He collected insects in Europe, travelling to Italy, Spain, Portugal and the Mediterranean. In the autumn of 1872, he left England on an entomological tour of the world, initially arriving at Philadelphia. In the spring of 1873 he arrived in California, where he collected insects until early July, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thaddeus William Harris
Thaddeus William Harris (November 12, 1795 – January 16, 1856) was an American entomologist and librarian. His focus on insect life cycles and interactions with plants was influential in broadening American entomological studies beyond a narrow taxonomic approach. He was an early agricultural entomologist and served as a mentor and role model for others in this new field. For 25 years Harris served as the librarian of Harvard University where oversaw the rapid growth of the library and introduced one of the earliest American library card catalogs.Elliott 2000 Life and career Thaddeus William Harris was born in Dorchester, Boston, Dorchester, Massachusetts on November 12, 1795. His father, Thaddeus Mason Harris, was a Unitarian minister who served at the church on Meeting House Hill and had also for a time served as librarian of Harvard. Harris himself received his undergraduate degree at Harvard in 1815, and then went on to study medicine there, receiving his M.D. in 1820. He ...

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), 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 arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). 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 ...
