Sawflies are wasp-like insects that are in 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 Tenthredinoidea are the dominant superfamily of sawflies within the Symphyta, containing some 8,400 species worldwide, primarily in the family Tenthredinidae. All known larvae are phytophagous, and a number are considered pests.
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.
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 and employ a wide range of feeding habits, both internally and externally, on their host plants.
Allantinae is a subfamily of sawflies in the family Tenthredinidae, and the largest subfamily of that family, with about 110 genera. The subfamily is considered to consist of five to six tribes, and are medium to large sawflies.
The genus Caliroa is a group of sawflies in the family Tenthredinidae. The larvae are slimy in appearance, and are sometimes referred to as "slugs" although they are insects rather than gastropods.
Monostegia is a genus of sawfly. The authority is based on the description by Achille Costa and Oronzio Costa, although earlier work grants this to Fabricius 1798., though the most common species, M. abdominalis, bears the authority of Fabricius.
Tenthredininae is a subfamily of sawflies within the family Tenthredinidae, the largest sawfly family. It consists of 28 genera, including the type genus Tenthredo. It also includes most of the larger and more colourful members of the family.
Tenthredinini are a tribe of sawflies (Hymenoptera), including the family genus Tenthredo.
Nematus oligospilus, commonly known as the willow sawfly, is a species of sawfly in the family Tenthredinidae. Native to central and northern Europe and Asia, it was first recorded in South America in the 1980s and New Zealand in 1997, and has also been introduced to Australia, South Africa and Lesotho. Its larvae feed on the leaves of various species of willow.
Eriocampa is a genus of common sawflies in the family Tenthredinidae. There are about ten described species in Eriocampa.
Monsoma is a genus of common sawflies in the family Tenthredinidae. There are at least two described species in Monsoma.
Fenusa is a genus of common sawflies in the family Tenthredinidae. There are about 11 described species in Fenusa.
Euura proxima is a species of sawfly belonging to the family Tenthredinidae. The larvae feed on the leaves of willows, creating galls. It was described by Jean Guillaume Audinet-Serville in 1823. The species was placed in the genus Euura in 2014 and was previously known as Nematus proximus and Pontania proxima.
Acordulecera is a genus of sawflies in the family Pergidae. There are more than 20 described species in Acordulecera.
