The Tenthredinoidea are the dominant superfamily within the Symphyta, containing some 7000 species worldwide, primarily in the family Tenthredinidae. All known larvae are phytophagous, and a number are considered pests.
The included families share the distinctive features of a medially narrowed pronotum, paired protibial spurs, and the loss of the transverse mesonotal groove.
