Tenthredinidae
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, which will distinguish t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anders Gustaf Dahlbom
Anders Gustaf Dahlbom (3 March 1806 – 3 May 1859) was a Swedish entomologist. Dahlbom was born in Härberga parish in Östergötland County, son of a military surgeon. He matriculated at Lund University in 1825, completed his filosofie magister degree in 1829, became a docent of natural history in 1830, acting adjunct of entomology in 1841, adjunct in 1843 and keeper of the Entomological collections and professor extraordinary in 1857. Supported by public funds, he made several research journeys, especially to northern Sweden and the mountain regions, where he first accompanied his teacher, the dipterologist Johan Wilhelm Zetterstedt, as well as to other parts of the country and abroad, and published his observations in various works, most important of which is ''Hymenoptera europaea praecipue borealia'' (1843–1853), a foundational work on the hymenoptera Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and a ...

Sawflies
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies. The primary distinction between sawflies and the Apocrita – the ants, bees, and wasps – is that the adults lack a "wasp waist", and instead have a broad connection between the abdomen and the thorax. Some sawflies are Batesian mimics of wasps and bees, and the ovipositor can be mistaken for a stinger. Sawflies vary in le ...
