Diabroctis is a genus of beetles of the scarab beetle family.
The whirligig beetles are a family (Gyrinidae) of water beetles that usually swim on the surface of the water if undisturbed, though they swim underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. The family includes some 700 extant species worldwide, in 15 genera, plus a few fossil species. Most species are very similar in general appearance, though they vary in size from perhaps 3 mm to 18 mm in length. They tend to be flattened and rounded in cross section, in plain view as seen from above, and in longitudinal section. In fact their shape is a good first approximation to an ellipsoid, with legs and other appendages fitting closely into a streamlined surface.
Ross Harold Arnett Jr. was an American entomologist noted for his studies of beetles, and as founder of the Coleopterist's Bulletin.
A bark beetle is one of about 6,000 species in 247 genera of beetles in the subfamily Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus Scolytus, namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the American elm bark beetle Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce ips Ips typographus. A tiny bark beetle, the coffee berry borer, Hypothenemus hampei is a major pest on coffee plantations around the world.
The Tenebrionoidea are a very large and diverse superfamily of beetles. It generally corresponds to the Heteromera of earlier authors.
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
The Zopheridae family of beetles has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches.
Ulmus castaneifoliaHemsley, the chestnut-leafed elm or multinerved elm, is a small deciduous tree found across much of China in broadleaved forests at elevations of 500–1,600 metres (1,600–5,200 ft).
Ulmus chenmouiW. C. Cheng, commonly known as the Chenmou, or Langya Mountain elm, is a small deciduous tree from the more temperate provinces of Anhui and Jiangsu in eastern China, where it is found at elevations below 200 m on the Langya Shan and Baohua Shan mountains. The tree was unknown in the West until 1979, when seeds were sent from Beijing to the De Dorschkamp research institute at Wageningen in the Netherlands.
Ulmus szechuanicaFang, known as the Szechuan (Sichuan), or red-fruited, elm, is a small to medium deciduous Chinese tree found along the Yangtze river through the provinces of Sichuan, Jiangxi, Anhui, and Jiangsu.
The Japanese Elm cultivar Ulmus davidianavar.japonica 'Mitsui Centennial' is a cold-resistant selection raised at the Morden Experimental Station, Manitoba, Canada, in the 1970s.
The Chinese Elm cultivar Ulmus parvifolia 'Chessins' is a compact Lacebark Elm used in landscaping.
The Chinese Elm cultivar Ulmus parvifolia 'Frosty' was intended primarily as a dwarf variety.
The Chinese Elm cultivar Ulmus parvifolia 'Geisha' is a dwarf variety.
The winged elm cultivar Ulmus alata 'Lace Parasol' was found by a North Carolina nurseryman growing in local woods. Removed to his yard, it remained there until his death, when it was removed again to the North Carolina State Arboretum in Raleigh by J. C. Raulston.
The Lycidae are a family in the beetle order Coleoptera, members of which are commonly called net-winged beetles. These beetles are cosmopolitan, being found in Nearctic, Palearctic, Neotropical, Afrotropical, Oriental, and Australian ecoregions.
Onthophagus is a genus of dung beetles in the Onthophagini tribe of the wider scarab beetle family, Scarabaeidae. It is the most species-rich and widespread genus in the subfamily Scarabaeinae, with a global distribution.
Diabroctis mimas is a species beetles of the scarab beetle family.
Sternotomini is a tribe of longhorn beetles of the subfamily Lamiinae. It was described by Thomson in 1860.
Phanaeini is a tribe of dung beetles in the family Scarabaeidae. There are about 12 genera and 200 described species in Phanaeini.
