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] |
Eriocampa Ovata (Woolly Alder Sawfly) Larva, Arnhem, The Netherlands
''Eriocampa ovata'', known generally as the alder sawfly or woolly alder sawfly, is a species of common sawfly in the family Tenthredinidae. The larvae feed on the leaves of the common alder (''Alnus glutinosa'') and the grey alder (''Alnus incana''), sometimes causing defoliation. Description The adult female is about long and mainly black, with the exception of the first two segments of the thorax, which are red, and the underside of the tips of the antennae, the inner side of the fore-tibia and the basal part of the hind femur, which are whitish. The head has numerous large puncture marks while the thorax has scattered smaller ones; the abdomen has faint transverse sculpturings. The wings are translucent with black veins. Adult males are unknown in North America, and rare in Europe, the females breeding by parthenogenesis. The larvae grow to a length of . They are white, apart from a brown mark on the head, and are covered with a glossy, white woolly secretion produced by e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Woolly Butternut Sawfly (Eriocampa Juglandis) Larvae
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack crim ...

Eriocampa Tulameenensis
''Eriocampa tulameenensis'' is an extinct species of sawfly in the family Tenthredinidae that is known from early to early middle Eocene lake deposits near the small community of Princeton, British Columbia in the Similkameen region. History and classification ''Eriocampa tulameenensis'' is known only from one fossil, the holotype, number "GSC No. 22688". It is a single, mostly complete adult of undetermined sex, preserved as a compression fossil in fine grained shale. The shale specimen is from deposits along the Canadian Pacific rail line in the Similkameen Country of British Columbia, Canada. The type specimen is currently preserved in the Geological Survey of Canada paleoentomological collections in Ottawa, Ontario, Canada. ''E. tulameenensis'' was first studied by Harington M. A. Rice of the Geological Survey of Canada, with his 1968 type description being published in the Geological Survey of Canada professional paper number 67-59. The specific epithet ''tulameenens ...
