Nematinae
Nematinae is a subfamily of sawflies belonging to the family Tenthredinidae. It contains over 1250 described species in ~40 genera. Members of this subfamily feed on a wide range of plants (over twenty plant families have been recorded as hosts) and employ a wide range of feeding habits, both internally and externally, on their host plants. Most groups of insects tend to have maximum numbers of species in the tropics and decrease towards the poles. The Nematinae reverse this trend, with the highest number probably occurring in the boreal forest zone. The reason is not fully understood but could be because of the abundance of species of willow (''Salix'' species) in the region. In 2014, species feeding on willow, in the genera '' Eupontania'', '' Phyllocolpa'', ''Pontania'' and '' Tubpontania'', were placed in the genus '' Euura'', reflecting advances in the understanding of their phylogeny. Genera Genera include: * '' Adelomos'' Ross, 1935 * '' Anhoplocampa'' Wei, 1998 * '' An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euura
''Euura'' is a genus of sawflies of the family Tenthredinidae, subfamily Nematinae. Some of the larvae feed externally on plants and some form plant galls on willows (''Salix'' species). In the case of the gall-forming species, when the female lays her eggs she injects a stimulant and the gall start to form before the eggs hatch. Most sawfly galls are hard and individual larva tend to inhabit the gall, feeding on the tissue and leave the gall to pupate in the soil. Most of the species are monophages (i.e., specific to one species of willow) although the type species, '' Euura mucronata'', is polyphagous feeding on over thirty species of willow. Most groups of insects tend to have maximum numbers of species in the tropics and decrease towards the poles. The Nematinae reverse this trend with the highest number probably occurring in the boreal forest zone. The reason is not fully understood but could be because of the abundance of species of willow in the region. In the Wes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemichroa Australis
''Hemichroa australis'' is a species of sawflies in the family Tenthredinidae. Description ''Hemichroa australis'' can reach a length of about . Head and thorax are bright red, while the mesopleuron and the abdomen are shiny black. This sawfly is similar to '' Hemichroa crocea'', which has a bright orange abdomen and legs. Larvae feed on alder (''Alnus'' species) and birch (''Betula A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus ''Betula'' contains 3 ...'' species). Distribution This species can be found in most of Europe.
